We are staying at RPR and I was wondering how early you headed over to IOA. I have read that some people were gettting there at 7:00 a.m. and I wondered what time they let resort guest in.
They let resort guests in around 8am. Waiting is a personal thing, some folks like to get there at 6am so they are the first through all the attractions and some like to get there at 7:30 and wait an hour or so. If you think about it that works out to be the same wait, just at a different part of the line. I would watch the crowd report threads and decide for yourself.
