No. But I am sure someone at the hotel can help you figured it out. There just isn't anything officially sponsored or organized anymore.
Don't think so. You need to take a cab and go. Talking of cabs in Cancun, always make sure the driver agrees to a fare before going anywhere. Typically, it's a higher amount coming back late night.
Club is ok. Nothing to rave about really. There is also a Mandala Beach Club. There are few other places in that area. I find them all average in comparison to clubs elsewhere.
It has been about 2 years but we visited Mandala with another couple 1 night. I liked it because it was stadium seating / tables so wasn't as crowded as the mass clubs. Prices were reasonable. We got a bottle of grey goose and a bottle of wine for a little under $200 (of course 'reasonable' is relative as TTR is free but those two bottles would cost way more at a club at home) There was a shady element. Random guys and girls wandering. Some were selling drugs and pestering us. Some were selling themselves ... yes ladies and guys. We paid a bouncer to be our personal bouncer for $60. He basically kept them all away and escorted the girls to the bathroom so they were never alone. Was the best move we made. Party was a lot of fun. Lots of groups of girls and groups of guys. Wasn't unbalanced as I expected. And our ladies attracted the groups of girls which enhanced the party. You could probably see why based on attached pictures End result is it was nice to do once. But have stayed at TTR ever since.
