The Mandalay Bay is a huge property and away from street traffic as it's the first major luxury hotel on the south side strip. Speaking from a Gold M life membership view point, the hotel has everything from fine dining to one of the best pools( The Beach). The service and staff are dedicated and try their best to make your stay pleasant.
Stayed 4 nights 5 days in one if the Luxury Penthouse Suites on the 62nd floor (highest) with a view of the pool and birds eye view of Vegas. Easily one of the best experiences in Vegas and never noticed any neighbors or noise the entire time.
Although an older property now, it still easily one of the more luxurious hotel casinos on the strip. Although the hotel and restaurants are great, I found the gambling a little lacking here. I haven't enjoyed the best success here playing but the casino floor is very large and open. I felt a number of the slots were dated and lacking variety if that's what you play.
