When we went last April, Toontown opened at 10:00 (one hour later than the rest of the park). I didn't notice when Adventure land opened. Maybe someone whose been more recently would comment if this has changed. FYI, we made sure we were at Toontown when the ropes dropped and the kids had the best magical moment. Mickey was right there shaking hands and taking pictures. You had to be right up front though b/c Mickey was quickly led away after a few photo ops. It was a special moment.
