I visited Coco Bongo in Cancun 10 years ago, we decided to visit this year, but already in Tulum.
The show is no different. I was impressed the first time, but now I'm not, everything is the same.
We purchased a ticket that included a "seat + alcohol".
Moment: they are checking the passport! And that your name would be on the card you used to pay for the ticket.
My friend bought us a ticket! If he hadn't come and showed his card + passport, they wouldn't have let us in.
Tickets are non-refundable, but you can change the date.
PS. It's still worth going once.
