In reference to Board Question #16849 on what to bring for your cruise... be prepared to tip. When we went, a lot of tips were expected at the end of the cruise, for all the various staff who attended us. On Royal Caribbean's site it tells you how much is expected - http://www.royalcaribbean.com/allaboutcruising/newtocruising/alreadyBookedCruise.do;jsessionid=0000W1zOlXFQRd-xNqlKnt0Po2p:v2krl5v8
If there are two of you going, this adds up to $217. This can be quite a shock if you're not prepared for it. Have a fun time!
