We had aft cabin 1604 with one of the largest balconies I have ever seen. Cabin had lots of storage. Slight noise above from the Windjammer...but nothing that would spoil the "Aft" experience.
Used JJ Tours in Costa Rica....He was wonderful. Book it...well worth the $$$..also Claudia Tours in Colombia...again she was knowledgeable. You certainly get alot for your money with both of these people.
