This was first experience booking with Airbnb and it was great! Lucky Star is a great host and let me know in advance everything that I needed to know. My parking pass was available at the security booth and check-in was smooth. I just need to give a credit card for incidentals which I never used. The MGM is attached via enclosed walkways and was really nice and convenient. The buffet at the MGM is really good, surprisingly, and very clean. I don't usually eat at buffets, but this was a good value and we ate tons of crab legs. The MGM casino is really nice and the air quality is better than in most casinos. There is a lot to do in the MGM and would suggest the Screening Room and the CSI Investigation experience. We had a small car that we rented at the airport which made it easy to travel around. The valet parking is free, and we just tipped a couple dollars each time we dropped/picked up our car. The pools are very nice at the Signature and we had access to the main MGM pool. We didn't stay at the MGM pool for very long since it was crowded. We cooked in the room for convenience. I would suggest that others who plan to cook in the room purchase a sponge, dish soap, and maybe some cheap pans in addition to what is available. I picked up a fry pan and skittle for $16 at an outlet store. There is no hotel service for towels, coffee, sugar, cream, etc. but this is fine because we avoided the $35 per day resort fee and the higher cost of booking directly. If you see a housekeeping person, just tip them a few dollars to get some extra towels. The Cuisinart mini coffee made great coffee and we just picked up good coffee, filters, sugar, and cream at Whole Foods.
I would definitely look at Lucky Star's rooms for a return trip to Vegas.
