THEhotel just feels different. It feels like you are not in a hotel on the strip, but actually are. It feels secluded from the noise and traffic, but it's actually right there in the middle of it. Everything from the parking lot, to the lobby, to the rooms doesn't feel like Vegas, but in a very good way (unlike Aria, which I do not like). Just a couple of steps and you are right in the middle of all the fun.
The rooms are really nice with a separate bedroom and living area. The bathroom is large and spacious, more so than other nice, high end hotels on the strip. For example, THEhotel's bathroom is larger than Aria's but on par with Venetian's if I remember right.
I particularly like the entrance to the hotel. The lobby area is dark and feels as if you are entering a private hotel that is exclusive to only you. THEhotel shares the same casino with Mandalay Bay as they are one so you can move between the two easily.
I'm glad my friends decided to stay here because I would've never known to book a room here on my own.
