Thought I'd better move the duPlooy's questions from the Ambergris specific board. I was wondering if anyone (especially you, Debbie) has any suggestions for keeping my parents (78, 79) happy and occupied for our 6 days at the lodge. My dad is very active but my mom has an occational hip problem that makes long walks not so pleasent. Would the Tikal trip be too taxing or are there all levels of tours available? How about the sites closer to San Ignacio? Thanks so much for everyone's input. This board is invaluable.
