hey all...just a quick question reagarding if my 20 year old son and his same age girlfriend can legally drink alcohol on the cruise. We're booked for Freedom o/t Seas, leaving Dec. 20th for 7 days. Looking at the brochure book though, there is an age limit of 21. Can we sign a waiver as mentioned in the book or is that just for the exempted departure countries ie: Europe, S. America.
