Came by for a 1 night stay the other night at the MGM and the experience was world class!
Signed up for e-mail offers and made a reservation for a regular room + $10 for an upgrade to an Executive Suite. Upon arrival, the line of ~40 folks was relatively quick at ~15 minutes. Did the $20 trick to my front desk agent, Paige, and she went to work, first upgrading me to a 1 Bedroom Suite, then to the Grand Marquis 2 bedroom, 2 bathroom pool table 1500+ sq ft suite.
The room itself was the largest and most luxurious suite that I've enjoyed in. There were a few minor hiccups, one of the in-room safes was non-operational and one o the 4 LED TVs were non-operational...all 1st world problems...
Check out was a breeze with Express Checkout via my Mobile phone.
The walk from Self-Parking can be quite a trek...do valet if you have a lot of luggage!
