All things being equal 99/509 will always be quicker (although it is relatively close) but it is also the less risky route. I have never taken I-5 from there (or Belltown).
The OP has pre and clear and is leaving in the morning so he can be airside at checkpoint 1 in less than 5 mins. I have flown millions of miles and still fly ~100k per year and have never waited at TSA at SEA for more than 20 mins (I also have pre+clear).
I do agree, the biggest risk is the ship being delayed (which happened a couple of months ago due to winds) but if the OP is in a cab by 730 (or even 8 ) he is going to make the flight. The next biggest risk is if they have checked bags but assuming they have priority access that shouldn't be an issue.
Not really no, and I worked in Belltown for 15 years often going to and from the airport. The only time the traffic was bad was when the viaduct was being demolished but that has long since finished.
Sorry, I don't mean to be sparky but the op makes that flight 95+ percent of the time.
If you were in a cab/uber by 730 you will be more than fine and probably spend an hour in the lounge. With PRE+CLEAR go to checkpoint 1 which is at the end of departures near the international gates. It has never taken me more than 5 minutes to get airside from there.
The short answer is yes, usually you should be able to make that flight. You would need to do self walk off with your bags and TSA Pre and/or CLEAR would help and quickly get a cab/uber, but assuming there are no delays you will usually make that flight. There will probably be a bunch of replies saying that it is impossible but that isn't true, I have flown millions of miles from SEA and for morning flights would leave from Sammamish (farther from SEA than pier 66) 2 hours before departure and never once missed a flight. Just know that if anything gets delayed you might miss the flight (but there are always more flights).
You choose 5 numbers which can be drawn in any order so the first ball has 5 chances for you to be right, the second 4, the third 3, and so on.
Also, I searched and couldn't find the jackpot size but I did see the rules which stats that a winner has the option of taking 50% now or have it paid over 40 years so whatever the amount divide by 2.
I have hosted a few and have one coming up next month. Usually 50 to 60 people show up but I have never gotten any perks (but I didn't expect or ask for any). I just do it because it is fun and I like to meet fellow cruisers.
I have one upcoming on the dawn with a pretty good number signed up. As mentioned above, it includes a shot glass exchange for which almost everyone has also signed up. Since they already made the investment they usually attend (and it is fun 🙂 ).
I have some few together that were well attended (I have one upcoming with quite a few signed up). I usually include an optional shot glass exchange which is fun and encourages people to attend.
