The ferry does run, but may stop before late October as it's not so great an experience in cold weather

It's a 25 minute walk from the Hostel to Neptune. Probably not more than 25 minutes from there to anywhere. And you can walk on the Freedom Trail for most of the course, or thru the Public Garden and Boston Common if you prefer, for only a few minutes longer trip

Agree that Myvatn is full of midges. From our first visit to Iceland in 2013 to our most recent one in 2019 we definitely saw more insects later on than earlier. Locals believe it is due to average temperatures rising due to global warming making the environment more 'bug friendly'

Boston is mostly known for Seafood. Lots of good pubs, too. It's a big city, anything you want, you can find. Boston Common is big. Let us know which hotel and how far you are comfortable walking and we can make suggestions

Leaving Boston for Plymouth in the morning isn't going to see much traffic. As soon as you get on I-93 South it should be quick, all the traffic is going TO Boston. Those two hotels in Braintree aren't great. I wouldn't recommend them to a friend unless they are on an extreme budget

For Husavik: What do you like to do? The Diamond Circle is popular up there. So are whale watches. A trip to Myvatn, maybe. Rent a car? I don't know the other area

Are you sure it's only 3.5 hours? That barely is enough time to get from the port to the Golden Circle area and back, no time to see any of the attractions. 7 hours makes more sense. I don't recommend using third parties like Trip Advisor/Viator, especially in places like Iceland where weather can affect plans 365 days/year, but I'm glad it worked out for you.

The Westin Seaport is the closest Bonvoy property to the cruise ship pier. Quick cab or uber ride, or accessible via public transit from Logan. 20 minute walk to the pier, or a cheaper cab or uber

I agree wtih @GeezerCouple. GYG is a third party provider and we try to avoid those, especially in places like Iceland where weather can always affect your plans. Trying to communicate to a provider thru a third party when time is of the essence is much more difficult than dealing with them directly. I know with the other third party that starts with "V" that you can usually see the actual provider on their website. Not sure if it's the same with GTG, but I'd try to figure out the actual provider and book directly.

Sea ice is rebuilding because the ice is calving off of the glaciers, and it has to go somewhere, so it follows the currents. Glacier coverage is smaller now than it has been in recorded memory. All BECAUSE of Climate Change

that kind of footwear should be fine for those excursions, if it isn't raining. If it is raining, and it rains about half the days in Iceland, you might be uncomfortable and wish you had low top hiking boots

Any places in particular? "The maritimes" is a huge area. You can google things like "average august weather in Halifax" if you want to see actual historic data

B, C, OR D trolley will get you there. They all take the same route to Kenmore Square station before branching off from there. Kenmore is a bit closer tot he ballpark than the Fenway Park station is, which is only on the D line.

There is also the MBTA Commuter rail to Plymouth. You will need a cab/uber to get to the Museum, though.

We loved it. We did it on arrival day, flying from the East Coast, figured if THAT wouldn't keep us from falling asleep on arrival, nothing would. And we were correct

Do both bus tours. Reykjavik is a very cute city, but you are unlikely to ever get to experience the wealth of nature Iceland has to offer again. The geysir is not as spectacular as Yellowstone, but it goes off much more often so you can get amazing pictures. We've been to Iceland 5 times and done the Golden Circle 3 of those visits, and the other sites the only time we were in that part of the country. Breathtaking

Taxis average $130-$150, and you don't have to wait for a bus to fill up or to get your luggage unloaded. But the bus is certainly simple

That's my old neighborhood! We ate at Larry J's once and never went back. But that was a long time ago. Smoke Shop is further, maybe 20 minute walk, and is excellent Q, and open late What day of the week? Fri/Sat gives you more late night options than other nights. I am assuming Fri/Sat, below: Legal Harborside is about a 10 minute walk from your hotel and is open until 11. It is the Flagship of the Legal Seafoods family and has an upscale upstairs and a more typical, but still special, downstairs menu. Harpoon Brewery is a similar distance, they do serve food, not sure how late, though SAVR is about 15 minutes away on foot, open until 11. Good looking menu, I've never been there, though Seaport Social gets raves from friends, they are open past midnight Strega is strong Italian, open to 11, so is Rosa Mexicano (but not Italian!) We've eaten at Committee a few times, and they are open past midnight Row 34 is one of our favorite Boston restaurants, and they are open until 11.

Sunny is not an Iceland company. The .nl suffix means they are a Netherlands company. Lots of good Iceland rental agencies, including Lotus, as mentioned by @Mr. Click We have done 5 land tours of Iceland, ranging from 2 days to 10. Driven on those good roads and on quite a few of the bad ones. And taken a Superjeep tour a couple times on roads that had river crossings or deep snow on them Getting a car with a little extra ground clearance is a great idea for Iceland, as it makes driving on those bad roads quite a bit easier

You might want to check that information yourself before you post it

Do you recall how much that cost? A taxi would run about $130-150 and might be even more convenient.

Carmines is very popular with tourists for their portions and prices. Not popular with locals who disdain the food. SO much better out there for Italian, even some with big portions and reasonable prices!

When we lived in Boston we went to NYC most long weekends. For years we stayed in or near Times Square as we revolve our visits around Broadway Shows. For the last 10 years we've stayed in TriBeCa, down in the lower part of Manhattan. Great subway access to midtown but so much quieter, with great restaurants and close walks to either river. Quite close to the 9/11 Memorial, etc, but only 20 minutes by subway to midtown

Westborough was what I was going to suggest. And maybe look into the Logan Express for parking and transfers if money is an issue. It will be slightly annoying to take a bus from the lot in Framingham to the airport and then take transit or a cab/uber to the port, but it will be much cheaper than parking at the airport or at the port. Then, when you return, do the opposite to get back to Framingham Versions of this might work for @Keith At Sea and @Birdnutty

#1 has great advice. Another option is to self tour the city and then take a taxi or the Flybus to the airport. Or go to the Sky Lagoon in the city and then bus or taxi to the airport
