We took our 17 and 20 year olds this June for 14 days. We all SCUBA...so that was our main focus on San Pedro (left the 8 year old home with Grandma). Also enjoyed fishing off San Pedro. We spent 4 days on mainland and wish we'd had 2 more nights at Chaa Creek. It was really fun doing the night hikes, day hikes, spa visit, Tikal, canoeing etc. Would have like to gone cave tubing but not enough time...so much to do! Have a terrific trip!
