Hello, i just got my united club card which makes me platinum level on hyatt.

I need to book atleast 5 rooms x 2-3 nights for may 2013.

I have tons of chase ultimate reward points which i plan to use.

Should i book now? (then i can cancel if some promo's come up?) or wait till early 2013 when promo's come out? Iv seen some recent promos but they all require stays before end of this year.

Also, would each room get the platinum perks?

thanks guys
