My husband and I have cruised both celebrity and viking. We are elite plus on celebrity and have done 12 viking cruises. We did the circumnavigation of Iceland last July when Viking was starting back up. It was a wonderful cruise. You will like it. As to the difference between Viking and Celebrity, it is more than the types of tours and closet location in the cabins. Viking is more laid back than celebrity. They never try to sell you anything. The Nordic spa down on deck one is fabulous and free. There are no photographers, no smoking, no umbrella drinks, no children under 18, and no casinos. You can eat dinner anytime you want (except for the specialty restaurants where reservations are required) and never wait more than 5 minutes to get in. Their buffet is actually quite good in the evening - crab legs and large shrimp are always there. On sea days there is high tea every afternoon with a string trio playing in the background. The decor throughout the ship is nordic and has some nice touches like a small viking museum and original Edward Munch artwork. There are heated floors in the bathrooms of your cabin. All cabins are balcony cabins - we like the dv4 category. Each deck that has cabins has a self serve laundry that is free. Detergent is supplied free also. It is a very different experience from celebrity - one that you should try.
