I did a tremendous amount of research prior to booking through VRBO and would have booked Signature directly through MGM, but they did not have availability for our final night 7/4 which was my mom's wedding. We chose Signature because we needed a full kitchen for wedding prep and separate rooms for our teens. Check in definitely was not what I had hoped for and 3 separate clerks made a point of saying "Oh, did you know you booked through a third party?" When I told them it was necessary due to the standard bookings being full, that didn't matter and we were treated rudely. We paid for our rooms just like anyone else and surely they have a lot of owner renters staying there. We were told numerous times even after check in time that there was a delay/check back. I finally asked what tower we would end up in and when she told me tower 2 we went to tower 2 from tower 1 with the rude tellers and were able to check right in. Go figure. We were on the 16th floor, not a Penthouse as we had been told with our original reservation. We tried to reach Las Vegas Suites 4 times that day and we were told they were closed on weekends. We didn't want to dampen our fun the first day so we finally just unpacked and settled in.
The room was very nice and what we expected with the exception of 2 broken chair backs, the 2nd room safe didn't work and the TV in the 2nd bedroom didn't work. Everything you have read was the same as expected with a wonderful large bathroom, safes in the closets, perfect kitchen for a week long stay, view of the rave party pool at MGM and was just what we wanted space wise for the week. The Las Vegas Suites contacted me the 2nd day and said they would credit us a small amount for the downgrade on the room type which they did as well as fixing the safe and TV.
The rest of the trip was great. We loved the Delights café in Tower 2 and ate there most mornings although we had not planned on it. The breakfasts were that good. We enjoyed having our own Starbucks in Tower 1 and the walk to the MGM did not bother us. It was long at night, but it was so close to the MGM pools that we loved that. We thought the Signature pools looked good, but we loved the lazy river so much that we just went there every other day. The food court in the MGM is really close and we ate there often. Wolfgang Puck was fantastic
The location at that end of the strip was perfect to access NYNY, Excalibur, Luxor, etc. We had a great time and would recommend Signature again.
