Loved the Infinity
4 of us went on the Infinity to Alaska May 2011 and loved it. We have been on Caribbean, Holland America and Princess as well. We found this ship to be the friendliest one we have ever been on. All staff smiled and greeted you even if they passed you in the hallway.
the Lido buffet was amazing!! Not well layed out, as it was spread out in various stations, but once you learned to walk all the way to the stern of the ship and around the other side of the food area, we discovered all the various treats. Ice cream was 'home made' and lots of flavours available all day with candy to top it off or just eat on the side. Desserts were so delicous and they had a Brunch Buffet in the main dinning room one day that was amazing. The dinning room food was good too, but the buffet upstairs just had so many choices, even stir fry and sushi in the evening.
We liked the night club upstairs, enjoyed their shows too. Started off the first day onboard after having lunch, with a tour of the ship with one of the program director staff and it was very interesting with a good way to get to know the ship. As we went by the coffee bar area she waved towards a display case of wonderful looking bakery treats and said those are "fat free" -- they are free and full of fat! which made us laugh! I would highly recommend it! Not as formal as Holland America, very good food similar to Holland Americal but maybe more choice, better than Princess.
You'll have a great time.
