It's not major, but an irritation. I have two night offers for DTG for July and August and both include $80 in freeplay. Anyway, I was double booked there for Sat & Sun, Aug 1 & 2. My wife says she'd like to use their pool Saturday morning and I know last time we did this, they were checking room keys for entrance. So since I have 2 nights in July and 2 nights in August I called to see if I could change my reservation to July 31 & Aug 1, that way I could get the room key Friday night. Not allowed. There must be 48 hours between offers. I said I only want two nights, but she claimed their system wouldn't allow me to do that. Oh, I could buy Friday for $99+ Oh well, I'm sure she can probably sweet talk her way into the pool.
