Caribbean Back to Back?

[Highlander1]

Friends are booked on the Caribbean Princess for 1/8/12 and 1/15/12, both 7 day Caribbean cruises which go to different ports. Cruise can be booked either as a 7 day because it departs and returns to San Juan after 7 days or can be booked as a 14 day because the ports of call are different.

 

The concerns are, do the menu's change from week to week, is the entertainment different, are the movies (MUTS) changed etc.? Like the idea of a 14 day cruise but not so much if its a replica of the week before. I would hope that advertising and booking as both a 7day or 14 day would make the trips and venues different. Anyone with experience in this matter?

Normally, when a B2B can be booked as two 7 day cruises, the menus will repeat the second week. Also the entertainment (normally at least 95% of it) will also be the same for both weeks.
