I don't know when the store closes usually, but I do know WoD doesn't keep strictly the same hours as the parks. When I've been there, they usually seem to open at 9:30, even when DL opens earlier than that.
woohoo, sounds great. Thank you. 8 pm is just a little early to go to sleep for me so it will be nice to do something. We'll be taking turns with the kids as there will be three adults, so each night two adults can escape and so some stuff at night.
Last week when we were there it was open until at least 10pm - Lego store and others as well. Parks closed at 8pm. We did excatly that - kids went back to BWPPI with dad and the ladies went shoppng.
