Joey - We did our first B2B on Voyager of the Seas last May and would love to do another. Our ship was alternating itineraries so we did a 5 day cruise to Bermuda, followed by a 9 day Caribbean cruise.
We had the same stateroom for both cruises but was told by RC that our stateroom attendant would move us from one cabin to another if we did not have the same room.
Turn around day was wonderful. We had a leisurely breakfast and sat on our balcony and watched the confusion on the dock, between arriving/ departing passengers and loading supplies on board for the next trip. The ship was deserted and we enjoyed just walking around for a bit and listening to "the sound of silence."
We tipped after each cruise and was glad we did. Even though we had the same dining room table we had a different waiter/ assistant waiter and even Head waiter.
RC operates on a 7 day menu plan so the first 2 days of the 2nd trip had new items on the menu then it repeated. Gave us a chance to try different things. The entertainment was basically the same - one different commedian but the same production shows.
We would do another B2B in a heartbeat if the opportunity presented itself.
