Saundra, Carnival Legend Dec. 2...yeah!
For Costa Rica we are going with cave-tubing.com, it's $45. pp. It sounds like lots of fun after reading dozens of reviews.
For Panama we are going with myfriendmario.com. Mario has answered my questions(and I had alot) and has been very helpful! You do have to send a deposit on this excursion which we are doing the locks and rainforest tour. Its around $60pp.
Hope this helps!
We are a group of 18. Can't wait!
