My wife and I are doing the same thing, second trip this time bring the children ages 12 and 8. We will be there for he two weeks of Christmas, we have booked cave tubing and zip lining but we booked it on a day when there are no cruise ships in port therefore it should not be as crowded. We also booked a day trip snorkeling and Caye Caulker. The canoe trip sounds pretty good also. I am sure we can find things to stay busy condo has a pool.
