Don't need to purchase the alcohol package unless you plan to excessively drink. Wine and beer was served with meals. A bit disappointed in the flights that were set up for us as they had 2 stops. would have preferred more direct flight thought the transfers were worth it. it was seamless.
Viking was great
Book your own Air
I think that most of the staff works very hard at accommodating the guests The Bavarian buffet was wonderful The motor coaches were very comfortable
Don't expect to find any security on the boat, because it doesn't exist! The excursions are very informative, but after awhile don't be afraid to go on your own.
