Just got back from Vegas, where we stayed at THEhotel for 5 nights. It's a beautiful hotel and the suites are absolutely lovely. We also had a great view from our room.

The pros:
Staff were friendly and polite and the service was good. Note that if you're a VIP guest, you may be able to get a late checkout for free. It's also extremely easy to get to the Luxor and the Excalibur from THEhotel as they're all connected. The Player's card is under the MGM brand, which means you can gamble at a number of different casinos and still collect points for it.

Things to consider (I wouldn't really call them 'cons'):
One thing to bear in mind when staying at this hotel -- it's located right at the south end of the strip, so getting to other hotels near the north end of the strip can be a bit of a pain if you're planning to take the bus. Vegas traffic (and the fact that the bus stops at almost every hotel along the strip) means that it can take maybe about 45 minutes to get from THEhotel to the Stratosphere or Circus Circus. If you're planning to cab though, then it won't be much of an issue -- the cab ride will be quick since you don't make stops in between. You could also ask the cabs to go by the back roads instead of going down the strip, which will speed up your trip a lot since you won't have to deal with strip traffic.

Also, because of its location, THEhotel is a bit quieter than the hotels located in the middle of the strip, which may be either a good or bad thing, depending on the kind of experience you're looking for.

We didn't find the food around THEhotel great. We tried the breakfast buffet at Mandalay Bay, which was pretty disappointing. Also ate at Mix, which is on the top floor of THEhotel -- were rather underwhelmed by that too. Didn't try the other restaurants though (and there are a lot of them at Mandalay Bay), so no comments about them. In any case, it's easy enough to get to the other hotels by bus / cab, or even to walk over to the Luxor (we tried the dinner buffet there, which was not bad).

Overall though, our stay at THEhotel was a great experience -- definitely worth staying there if you bear in mind the few points I mentioned above.

This was the cleanest, friendliest, most accomodating, very attractive hotel and great for the price. Each room is a suite. and its connected to the Mandalay Bay resort and casino. but its on its own with service and I loved this place. Only thing i didnt like was the pool was so crowded, but thats not their fault..loved it would stay again.

Stayed at TheHotel during Christmas visit and enjoyed it. The rooms are nice and mine was clean. Housekeeping staff were very nice and assisted whenever we needed them to. Did notice during check in that the lines were long and not many staff working during check in. Not sure why. Other than that the customer service issues that some of the other individuals have mentioned did not happen to me. For me it was a good stay, nothing really super great nor bad to say. Would stay at this property again in the future.

Had a great room overlook the stip in the middle of the hotel section towards the top. If you want a stunning view of the strip, pay the extra bucks for a view room, high floor. TOTALLY worth it.

Nice, standard hotel rooms, clean and comfortable. Nothing bad to state. Would stay here again. Loved being at the end of the strip. Walked its entirety more than once.

There is an aquarium theme to the place, and in fact there is a very cool aquatic marine center in the facility. Amazed at the large tank room. Its like you are in a bubble on the bottom of the ocean.
