Discover Scuba at Chankanaab

[kristap]

Hello all! I'd like to do a Discover Scuba experience at Chankanaab. There's Aquadventure, the one on the Chankanaab website, but there's also a different vendor offering scuba via Viator.  Has anyone used either or both vendors?  Any positive or negative experiences with either?  I'm looking at Aquadventure because their price includes park admission and is a bit cheaper than the Viator option (which doesn't include park admission.) There's also a $10 massage add-on to the scuba / Chankanaab option that I'd love feedback on if you have any.  I am SO close to pulling the trigger! Thanks!
