My navigators show both Sunday and Monday but it sounds like Monday works best. Works for me. You have to reserve your spot at Guest Services and from what I read on some thread, they spots fill up fast. Not sure if one person can make all the reservations - well, no I guess they would need your KTTW. Anyway if all agree, let's reserve our spots for Monday at 2:30! By then we'll all be nice and relaxed and we'll know each other's faces!!! Can't wait - just 72 hours!
