I'm going to be hitting Volcano Bay on a Thursday, Universal on a Friday, and IOA on a Saturday in a few weeks and all the parks appear to open at 9am. I will be staying at Cabana Bay and will have access an hour early... is this good at each park each day? Also, how is the best way to arrive. I am a bit confused where we will need to go to gain entry into the park. Only a few attractions are open in each park. Do we ride between Universal (Diagon Alley) and IOA (Hogsmeade)? Is there a specific entrance that is better?
