I was there at a pretty busy time last August. Had a 7:35 AM ADR, got in at 7:25 and did not rush at all because we were a large group. Left in about an hour after using bathrooms and such, walked to MK and made it in time to watch some of the opening show from outside the turnstiles. So we were at the back of the pack for RD, but still in good shape overall. We weren't racing for a headliner, just trying to make good time on several smaller rides, and we did.
