Mark is a great host, very responsive to any questions. He confirmed the request quickly. He was gracious is offering us late checkout on the last day because I had to leave early and my guest had a later flight.
A few points of information for future guests: So these are condos located in one of 3 high rise MGM Signature resort properties. Gated with security entrance off Harmon Drive. When you arrive you need to go to tower 2 which is the main check in spot. From there it works very much like a hotel in terms of going to you tower and finding your room. The rooms all have nice views of the strip, ours had both jacuzzi tub and shower. There is mini kitchen (fridge, infrared stovetop, microwave, coffee maker). There is a small cafe in tower 2, that you can call down and order food from up until I believe 7pm. Due to Covid, they make you come get the order, do not deliver to your door. The whole process with everything was pretty easy, with the exception of Valet. I am not sure what exactly was going on but they had a huge electronic sign posted outside the guard shack that consistently said "valet full, park at a garage down the street". We didn't have to do that but I could see that being annoying if I had a ton of bags I had to haul down Harmon to some garage. Other than that, everything was great.
