How I did it: my mom and i took a trip to mexico in september and just knew we would have to try this. its the best money i've ever spent, the whole experience was relaxing and magical. we booked our session at xel-ha...i'd heard positives and negatives so i was a bit weary but everything turned out amazing.
Lessons & tips: try to get in the smallest group you can. we had 5 total and i felt like we got so much time with the 6 dolphins that were in with us.
