My mom and I are planning to visit WWoHP for a (half) day in December and I want to go to both Diagon Alley and Hogsmeade. We want to enter through Universal. I've heard that we will be able to buy a ticket for Uni only but take the Hogwarts Express to both sides of WWoHP. My question is about exiting the park. According to Touring Plans, the wait to get on the train to go back to Uni will be an hour long. Does anyone know if we'll be able to exit directly from IoA? Honestly, our exit will decide which side we visit because I don't have any desire to waste an entire hour just waiting to get back out. We only have half a day (we won't be doing all the rides, mostly just wandering around). Thanks in advance!
