Stunning surroundings and service. At about midnight my daughter couldn't find a blanket so we dialled zero and someone brought one up within 5 minutes.
It is at the end of the strip but there is a free and very frequent tram service that whisks you in air conditioned comfort to Luxor and Excalibur.
We walked through most of the hotels and found some of them tacky and tawdry by comparison with the Mandalay Bay.
Every hotel has a theme or interesting thing or feature, eg New York New York has a huge kids games arcade and a roller coaster ($14 a go, or you can buy a day pass for $25). The Mandalay Bay has its amazing pool complex and the best selection of restaurants. There isn't any MacDonalds etc like in some hotels but still a wide range of choices, from Citizen which serves sandwiches and muffins through House of Blues and the fantastic and good value Wolfgang Puck restaurant Lupo, to some very posh places at the top end.
The pool is very busy in August. Really if you want a nice place to sit for the day (without shelling out $400 or so for a cabana) you HAVE to get there by about 9am at the latest - the pool opens at 8 and we made sure to get in the queue before it opened each day. If you come in at 10:30am you will struggle to find any sunbeds. The accepted practice is you put any personal item on a bed and you can leave it to go off for breakfast and it will be marked as yours. There are staff who will try to find you a place, and there are signs saying if you leave your bed unattended for over an hour it will be deemed vacant but I didn't see anyone's stuff being moved. We stayed around our little "camp" all day, there are waitresses who bring food and drinks to your chair, burgers, salads, sandwiches and such, for around $10, and $4 for sodas. You can buy bottled drinks for a bit less from the shop that sells tubes ($20 for a tube that is $6 from the Walgreens on the strip) (but they are Mandalay Bay souvenir ones - and by the way the man will inflate your own tube with his machine).
The pool and lazy river have lots of people in them -but not in a way that makes it an unpleasant experience - everyone was very friendly and ready to have fun together.
Everyone at the hotel and the pool and the restaurants is very kind and helpful.
ONE bad thing: the wifi is hopeless. Only really works in the room, otherwise it keeps logging you out and making you go through the registration process again. We went to the Bellagio for dinner and their wifi is completely open for anyone passing through, free, open, fast and easy, as you'd expect in a First World country. I really don't know why Mandalay Bay, who get everything else so absolutely perfectly right, get this one thing so annoyingly wrong! We relied on WhatsApp and Facebook messenger to keep in touch with each other and the execrable wifi service at Mandalay Bay made this very difficult.
