Our first Viking Ocean cruise is this coming summer: July 2023. I have sailed on Regent Seven Seas. So, my point of view is just from booking and cost of the two cruises for now. At first look, Regent Seven Seas does look a lot more expensive. But when you compare actual cabin to cabin and amenities, Regent comes out ahead in booking and costs. Excursions, for example: Regent has numerous included excursions while Viking only includes an introductory excursion (some on foot, some by coach/van/bus) at each port. If you are in a port more than one night, you get 1 excursion that does not include food or entrance to any museums or experiences. Regent, on the other hand has several included excursions every day and your only limit is your own schedule. Regent does off different levels of excursions that you pay extra. My experience with Viking, on the other hand is unless you are booked into a Penthouse cabin, you will be arranging your own excursions with third party companies. I guess this is OK for some, but it does create a class differential that feels like something from the Titanic era. From the get go, Viking will not service you unless you book the top tier suite cabins. OK, so you book a top tier cabin, you book book excursions and then you have to book an expensive beverage package. I have traveled on a Viking River Cruise. I'm not a huge wine snob but the regular house wine served on the Viking River Cruise was far, far inferior to the wine served with lunch or dinner on Regent. And, if you want a cocktail before dinner or after dinner on Viking and don't have a the drink package, costs of drinks will be added to your final bill. Viking house wines are not nearly as good as the Regent wines. Regent also offers business class flights, which is important to us if we fly anywhere outside of the Continental US. When you have an 11 hour flight, the economy section of the plane isn't even healthy for 55+ passengers, the demographics of both cruise lines. So, you pay extra for the upgraded flights, which is at least $500 per person and often more. So, now we are up to paying for a penthouse cabin, paying for a beverage package, paying for all but a few excursions, and paying extra for upgraded flights. Lastly, let's look at payment requirements. If you are a first time Viking passenger or you don't know to ask, your final payment for the cruise will be 3-6 months after your booking. If you are like us, you often book cruises 1-2 years in advance. Regent does not expect payment until 3 months before the sail date. Honestly, we just don't like the pressure or attitude of this from Viking. All this before we even set sail. I will be comparing the actual sailing experience of the two lines. I did note that the Viking crew were much, much friendlier and passengers seemed friendlier on the Viking River Cruise compared to the Regent cruise but I will hold judgement on that to see if it's a River vs Ocean situation on Viking.
