Hello. We are planning 3 day trip to Universal/IoA from 8/21 to 8/24, and there is no Early Park Admission to IoA for those dates. There is Early Park Admission for Universal for all three days. We are staying on site and would have EP. Would it be better to go to Universal with Early Park Admission first, and take Hogwarts Express to IoA when it opens or should we wait at IoA for opening gate? Thank you for your help.
