In February 2016 we are saving approximately $2,000 in total (3 of us) by doing a 4 night/3 night B2B Bahamas Cruise instead of a 7 night Eastern Carribean Cruise.
Pros: $s saved and two stops at
Castaway Cay
Cons: only ports are Castaway Cay (twice) and Nassau; also hassle of disembark and reembark at Castaway after first cruise.
We have sailed 6 times with Disney and this is our first B2B. We are giving it a shot to save the $s this time.
