As some of you know, I am a little bit fed up with PC/IC and am thinking of changing, at least some of my over 100 nights. I have been thinking of Hilton and SPG as a supplement or even my premium program. I have tried to read about both programs, but it is still not clear for me what is the greatest of them. However it looks like SPG will cover my stays where there are no PC/IC beter than Hilton. It also looks for me that SPG has better "luxury" hotels than Hilton, or am I wrong? (I mostly stay at IC's and CP's.) Ooooh, I have a love/hate relationship to this... :-D Maybe this is the wrong forum... I take the chance! PS. I am mostly interested in upgrades and the "elite-perks" as I travel mostly for business. Thanks in advance. Xxx.
