I am looking at the Myvegas rewards and I understand that rewards have to be used in 90 days. 1. For the hotels, if I get the reward now, does that mean my stay has to be within 90 days or the reservation made in that period? The dates I am looking for is open on their calendar. 2. Looks like the buffets require a one night stay. If I do two nights at one hotel that is not MGM and have the one night reserved at an MGM property during the week would that count or is the reward only going to work during the period of the reservation? What I am looking at is getting one night at Mandalay Bay, which would be 67,500 points and then looking at a Buffet during the time I am there. I am debating on staying either at Flamingo or down Fremont St for my other nights.
