Our stay at the Signature was pretty fabulous other than a few things that I will discuss later that caused a minus one star. The room was gorgeous. Very clean, all the amenities advertised, fabulous. There is an indoor air conditioned walkway to MGM. You also have full access to all the pools at MGM and Signature pools. Cabanas here are much cheaper than the MGM and the pool is quieter. It is nice to have all the options. This is a smoke free hotel which is a really nice break in Vegas for those that don't smoke! It is also a no gambling hotel so you don't have to wade through all the people in the lobby to get to your room. The jacuzzi tub had to be the favorite of the weekend. My complaints were minor and would have probably rated the stay 5 stars if not for the long check-in line. Which brings me to the (few) negative aspects:
The reasons I knocked off one star: Check-in took forever!! We arrived around noon on Friday and while we were super happy to be able to check in early, it took forever to do so. The reason was that they had only one person checking in guests. On a Friday. In the summer. In Vegas. While 2 other concierge people just stood there staring at the line. A better use of staff would be more people working the check in line.
I was also told we could have 4 waters sent up to our room a day in check-in but when we called were told we only got the 2 in our room. But you could grab water from the valet, pool, and gym so we were covered in the end and that is more than other hotels offer.
I also didn't like how they tried to shove the private more expensive cars down your throat acting like there were no cabs when in fact they keep the cabs in line further down and out of site and only call them up once you deny the car service. A little annoying to go through each time considering the number of cabs one takes in Vegas
But all in all, out stay was great and we will be staying there again next time!
