It makes sense to not have everyone go to one location at the end of the day. But how do you know which place to go to, do they tell you? And what if you make purchases at several different places, can you request that they send it all to one location?
As for sending it to the hotel, thought I'd read that the purchases would be available for pick-up by 8pm that same day. If it's not available until the next day, we nay have to carry some of the kids' purchases with us (ie. toys the kids will want to play with in the room.)
