This was the 5th time my husband and I have visited Las Vegas and we decided to try out the Mandalay Bay hotel this visit! We have not had very good luck when it comes to clean hotel rooms in Vegas! Last year we stayed at treasure island and our room was disgusting and the staff were not very friendly! I am super picky when it comes to having a spotless hotel room and Mandalay bay met all my expectations:)! They also had one of the most friendly staffs of any hotel I've ever visited! We were very impressed with this hotel and will definitely be back!!!
