I booked a comp room for MGM Grand Sept 8-12. Gotta pay for Sat night. While Vegas surfing today I noticed MGM was sold out Sunday Sept 9th. Does anyone know why MGM is sold out that weekend? I did not see a big concert or anything going on at the grand arena at that time. It is week 1 of the NFL but that does not explain a Sunday night sellout. Just wondering if there is a cowgirl rodeo or porno convention going on that weekend. It might alter how I pack. Thanks.
