The 1st to do, is take the 3 rivers, at the beginning take the more dark, 2nd one the Maya and by 3rd and the latest the manaty...after that focus to enjoy all the park!
When snorkelling, head to the cafe area under the bridge... The big fish hide there (3/4ft long) and wear flippers on the lazy river when in a rubber tube. If you fall out of the tube your screwed!!
