I am Hilton Diamond until March 2011. Really don't have a ton of stays, but tend to spend $5,000 per year at Hilton Hotels. Will Starwood automatically match me even if they don't see a lot of stays ?

Also if I wait until July 2010 to try and get the match - if accepted when would it expire ? My plan is to get Starwood, then Hyatt - then get Hilton again.

Thanks
