We (2 adult sisters) did a B2B on the Dream (3n/4n) in December 2015 and really enjoyed it.
For shows, we only went to each once: we spaced them out over the course of the 7 days, deliberately deciding which to do when. On the no show days we took advantage of the time to relax, explore the ship, do the photography session and character meets on at that time,etc. It worked VERY well.
Our first Nassau day we treated as a t=day at sea and did not even get off the ship. take that back, that may have beent eh day we walked to the nearby Starbucks... so lets say we did not leave the port
If you get the cruise photos package (we call all photos on USB stick), you can prepurchase the package for the first cruise online and get a discount, and then on the second cruise bring your receipt from the first cruise and they will let you buy the same package for the second cruise for 1/2 price. You can only do it on board though. Remember to pick up the USB at the end of EACH cruise.
On each cruise we booked a placeholder for an undated future cruise; we have since moved that to specific crusies: B2B on the Fantasy (yep, two weeks on board!
) in December 2017.
We did not run out of things to do, and in fact there were still some things we have not managed to do, and those were our 3rd and 4th cruises.
For switch day.
We had the same stateroom, deliberately booked that way.
At dinner the last full day on board the head server came and quietly asked us how things were going and if we satisfied with our table and servers or wanted to change; we were fine with them so stayed with them. It was actually pretty neat having them "again" since they alreade knew our preferences.
For switching: the last full day you receive a letter explaining what you need to do.
We left our luggage in our room, no need to repack, since we were staying in the same room.
We took a small daybag with us for things we needed or thought we might in the terminal. Also things to entertain us.
The letter said we had to be off by I think it was 915. We had late breakfast so this worked well. We walked off, went thorugh US Customs, then back upstairs into the main part of the terminal. We had to wait a bit until they opened a checkin counter. Then we checked in and were directed over to where the conceirge people waited.
The CMs apologized for the wait -- there was a film crew on board and that was causing the delay (we saw the crew filming at different places thorughout the 2 leg cruise). Eventually we were led back onto the ship; I think 11-something.
We basically pretty much had the ship to ourselves (well, except for that film crew, CMs, and about 20 B2Bers) for a while before they started boarding for the new cruisers.
We enjoyed being able to just relax and not have to do things that day -- no visiting dining services, we ate lunch when the restaurant opened, etc. Muster Drill takes time but is no big deal to do again -- I would rather repeat it lots and lots and know what to do should their be an emergency than not have "practised" enough so you forget when it counts.
Bottom line: we really enjoyed it and recommend it. Our next cruise will be B2B 7n on the Fantasy: eastern and western Caribbean.
