Hilton Diamond Status after 7 stays

So I've decided to switch my hotel allegiance. I have nothing but rave reviews for the Starwood program and I will continue using the Starwood Amex. However, Hilton's offer of Diamond Status after 7 stays between 4/1/10-6/30/10 is too hard to pass. I got this offer with my welcome packet for Hilton Silver last month. After a month of wavering, I've decided to go with Hilton.

Hilton Diamond is Hilton's top tier program which is equal to Starwood Platinum. As a Diamond, I will get club access, free internet, free room upgrade, 50% points bonus among other things. After taking a look at my travel plans from now until end of June, I should have no problem qualifying for Diamond. I hope...
