We all know free valet parking is gone. This is probably just fine if you know the layout of the property and parking garage and don't have a problem with self-park ($10/day). If not or if you're a bit weary after a day of travel it might be a major pain. Either way, from the moment we turned into the Mandalay Bay entrance off the strip it took us an hour to get to the lobby. Not cool after a long drive and day of work. We also tried to expedite our check-in by using the mobile scan check-in option...but it didn't work. We ended up having to wait in line. Same deal when we checked out. Mobile check-out kept bringing up an error so we had to deal with a Sunday late-morning check-out line.
Once we actually made it up to our room we were impressed with the desk set-up (great for a morning of work), high floor, and the general ambiance of the room. After unpacking we made our way down for a late dinner and found that our only option for a decent sit-down dinner and drink was the new Libertine Social space. This did the (expensive) trick (shared salad + pretzel + two drinks for $57 + tip). Played some poker for a couple hours and then decided to call it an "early" night and enjoy a shower and decent night of rest after a long day. This is really, really hard to do when the water in your room is shut off. We tested toilet, sinks, and shower. Nada. We called down, connected after about 7-8 minutes and our options were: 1) you can have the water in the mini-bar complimentary or 2) you can change rooms. Given the options we opted for #2. We were *not* happy about packing everything up and changing rooms at 2:15am after such a long day. They comped our resort fee but the whole ordeal left us annoyed. By the time we settled in our new room (21 floors below) with a parking lot view it was after 3:00. F-that.
TL;DR Rooms nice enough but everything else went wrong and/or too expensive.
Oh and a box of 10 tampons runs you $14.05 on the property. That just seems wrong.
