I have been hilton gold for about 2 1/2 years, I wrote to hilton yesterday inquiring about a fast track to diamond and they told me that I could be upgraded to diamond with 21 nights by July 9, 2012. I already have a 7 night award stay later in april and a 2 night stay planned in june. does anyone think its worth doing some cat2 matress run award nights to get to diamond. all my travel is non-busness, next year we are planning 8 nights in london and 8 nights in dublin on award stays so it seemd that being diamond might be beneficial but at what cost. I am in souther california so there are no cat 1 hotels nearby i could use.
