My wife and I visited this pool while staying at the Mirage April 30th to May 4th, 2015. We booked several months in advance, and knew that this would be a busy weekend in LV. We decided on staying at the Mirage based solely on their advertised offer of free entry to the Bare Pool for hotel guests before 12pm. We figured this was an adult weekend and we could use some rest and relaxation. We read some good reviews about Bare and decided to pursue it. The service was good, the food was decent for pool food, and the drinks were good, but overpriced- which is Vegas normal, I understand. The atmosphere was very relaxed, not unexpectedly small and more gents than ladies. We didn't really care about that since we went as a couple, but I mention it more as an FYI. There are two problems in particular that I am taking issue with. The first being that I was charged $50 to get in, in spite of the fact that this was totally contrary to what was advertised on their website. I mentioned to the 20-something kid at the register that this was the case and he acted like he could care less and said that's what it is because it's "a busy weekend," end of discussion. I decided to pay anyway since our mind was already set on visiting this attraction, as was the other couple's that was with us. We all rented chairs (4 total) for $150 each, with the agreement that we needed to drink and eat the minimum price of the chairs or pay the difference. This was an aggressive goal but doable, so we proceeded. After agreeing to the chair rental, we were informed that we would also be charged tax and a mandatory 20% gratuity, which we had no problems with, but we could have been told beforehand in case we didn't like the ~35% increase in original quoted price. Regardless, our server was good and we tipped her more than what we had agreed to, but that's not where the second problem lies. Our otherwise good time was ruined by some "Service Fee" that was tacked on to our bill that was never once mentioned before our rental agreement. Really, what in the heck is a "Service Fee?!" We obviously paid for our food and drinks, and we generously tipped the server, why is there this surprise fee in addition to all of that? This came right at the very end when it was time to sign for the bill. I chose not argue about it since I am sure it would not have been taken off, so here I am warning all of you. Needles to say, we did not go back for the rest of our stay. The Mirage is supposed to be a world-class resort, and the stunts they pulled both with the FALSE ADVERTISING of free entry for guests and a surprise "Service Fee" after spending over $800 for several hours at the pool is just plain wrong. I could expect this type of poor treatment at a bordertown dive bar that is frequented by rowdy college kids, but for a property that prides itself on being a higher-end resort, like the Mirage, this is totally unacceptable!
