We have never had an issue getting into Epcot through the IG, never did an ADR but we have always been let through before the official opening. One time we were let in and we were headed to Soarin. We rounded the corner to head into the Land and there was this massive crowd being held back in the breezeway. We were all like hurry...we made it in before the massive herd came in behind us. Another time we went in and rushed to TT, got there before the massive crowds again, only to be told it was down and they didnt know when it would be back up. All that rushing for nothing lol
