Will I have any problems if I check in at two hotels (say Park Inn and Country Inn) on the same night? I'll briefly be in proximity of cheaper properties, and would like to do a mattress run to take advantage of the promos. I will do everything in person, no cheating.

Has anyone done this? Anybody see anything in the T&C that would disqualify from the promos (I don't) ?

Also, can I check out immediately or, say, an hour after check-in?

Thanks!
