Maya consistently books some of the best DJs in the game, and I really can't complain about that! The drinks are decently priced for a Scottsdale club ($14 for a huge vodka/soda at the dayclub) and yes it can get crowded, but that's part of going out in Old Town! Try being at Omnia or any other place in Vegas and not being nudged a few times.
My friends and I got a table this past weekend, and other than an initial greeting and a couple drive bys, our servers were nonexistent. We waited about half an hour after our bottle was finished and nobody came around again, so we ended up just getting more drinks from the bar, which was fine by me. The bartenders were super friendly and efficient. Also we were all a little surprised that the pool wasn't heated! They had the most amazing floaties - unicorns, swans, rose bottles for those basic girls :) - but it was wayyyy too cold to get in! In about a month or so this won't be an issue, but for now it's kind of a bummer to come to a pool party and not be able to get in. I'll definitely keep coming to Maya for events, but I don't really see the point of paying for bottle service if you're just getting the bottle and not so much the service aspect.
