Stayed here one night on my last trip as I extended my stay one night and couldn't extend the rate on my other reservation. My wife and I have debated staying here but never did so it was a good chance for me to evaluate for 1 night to see if it was worth staying at on our next trip.
While I do like the high ceilings of the casino I don't like the fact that checkin is basically in the casino and there is not a dedicated lobby like other places. Other issues are I arrived to checkin at 12:40 and because it wasn't 1pm they charged me an extra $20 for early checkin. I've stayed at 4 or 5 other properties in Vegas (mostly MGM ones) and always checked in in the morning and have never had to pay this extra fee. In fact a week earlier I checked in at 9am at the Monte Carlo and it was not a problem. That in itself will keep me from staying here again but beyond that this is just a very odd building. My impression is that great strides were taken to focus on the exterior of the building despite what it would do to the interior. What it resulted in is very long (even by Vegas standards) halways with countless crooks and turns and overall a very disconnected feel to the building when trying to get from point A (your room) to point B (anywhere else).
Room was nice but the other things will keep me from staying there again.
