We did it on the Liberty in March and are set to repeat that same cruise in April .....and the anytime dining is very nice.
We had plenty of time to do anything we wanted and then go and eat without being restricted to a certain time.
Especially when getting back from excursions, it's not a hurry up situation.
Besides it pretty much what we do at home.....sometime within a 2 hour period at home also......
We were just on the Liberty the 29th of August sailing and the anytime dining worked very well for us. Some nights there were 6 of us, 5 of us, 2 of us, you get the picture. If part of the family had something else to do they did it and ate earlier or later. We asked for Bagus each night and were accomodated, he and his team are very friendly and efficient. The waiters have to be very organized in the anytime area since they have as many as 8 tables going at the same time with different people each night. the Liberty is a great ship we have been on her twice. Enjoy your cruise.
