I tried to book it the day we checked in and the CM said he couldn't book 2 rooms because my oldest would be 18 and so he'd have to split everything in to 2 reservation numbers, 2 deposits, 2 dining credit pools....etc. He said they would "try" to get us in the same building/floor...etc but since he'd be 18 they could no longer guarantee it. Odd thing is that he 'rooms' with my 2 younger sons who are under 10.....so the 2 separate rooms/dining credits....etc won't work. If I book my 18 year old his own room....well that's a lot more since we'd still need 2 connecting for my 2 dds and 2 ds's.
I called back and booked it the other way but after 4 days at the parks we called and cancelled it. It's way too hot for us in September and almost everyone we encountered was irritated, maybe because of the heat? Oh well, we'll see if we can't get a FDing ressie next year if they come out with a code for October or November, if not....we may just get a room only.
