Thanks OP, I went ahead and cancelled some reservations I made as they were for before 9/15 and wouldn't have counted. Im also on a SPG 2x stay Credit per night , so I'll stay at SPG before 9/15 to renew my Plat with them and then over to MR where I have 17 nights already booked.

MR gave me the 20 for 35k, SINCE the promo lasts till 1/31/07 Ill wait to complete my last 3 nights till after 1/1 so that it will count towards my Plat renewal for '08.

Of cause if SPG,HH or MR is much cheaper for any particular night in any given city that will have some weight as well. SPG 2x on Stays is good till 11/30. So no reason I shouldnt be able to get everything in with proper planning.
