I’ll be a guinea pig here and book an MGM property for a May convention via the convention website. I anticipate earning Marriott points and night credit for my stay, but I will report either way. I am sure there will be data points elsewhere. Other options I have are Four Seasons (which is a bit far south for me) and this Westin people are talking about (Wynn, Aria, etc already sold out at the conference rate, and too expensive otherwise)
