I've done a couple of adventures about this play. I mostly bought it for the tortle race though. It was my second character ever as a player. Been DMing since I was 11 and this play reminded me of a character which some should know (Benjamin the Turtle).
It's smooth, not that hard to make happens within the expected hours and it contains a lot of cool exploration around islands.
In itself, it makes for a good run and discovering the fauna and flora of Chult on the side is actually not a bad idea.
Good document, highly recommend since it's a charity donation.
