Firstly, a general thank you to the VMB - I've been reading avidly for best part of a year and I've it's been a massive help in learning about Vegas from the regulars. I'm making my first trip to LV in three weeks- staying 5 nights at MGM Grand. We've prepaid our room in order to keep our credit cards clear- does this affect the accrual of Tier Credits onto the MLife account? I plan to make the MLife desk the first port of call once we're all checked in, get my card and sign my wife up and join the accounts and in effect we've already made the spend because the room is paid- but do the TCs only come through night-by-night? We're in a Terrace Suite so if we got all the points in one go this would move us up to Gold and get us the bonus multipliers on Express Comps from the outset.
