Well unlike other reviews I read prior to my stay in Monte Carlo I have no complains at all! Me and my boyfriend stood in Monte Carlo for 5 days May 19-May 24. Check in was at 3:30 but we got there at 9:30 am and we where helped right away! We got a room in the 30th floor and it was really quiet the whole time! We didn't hear anything coming from the room next door and we hardly saw anyone in the hallways all week! Me and my boyfriend are not picky at all and we thought Monte Carlo was great! Good location and overall a nice hotel! If and when we go back to Vegas we would def stay in Monte Carlo again!
