Update: This post only covers the area of Hogsmeade and Hogwarts, NOT the new Diagon Alley or Hogwarts Express. Obviously some tips in this post are now outdated. However, many still apply. If you have purchased the 2-park ticket so you can access the entire Harry Potter experience, then I would suggest the following:
1. Enter Universal Studios first. With Diagon Alley being new, it will fill up very quickly.
2. Hit Ollivander’s (now located in Diagon Alley, it appears) and the new ride, Harry Potter and the Escape from Gringotts, first. Again, it’s new, so it will attract riders quickly. Don’t forget that Ollivander’s also quickly gets a long line.
3. When you are finished in Diagon Alley, take the Hogwarts Express over to Hogsmeade and enjoy your time there. I’m guessing that the new area will be more crowded than the old, but remember – if it gets more crowded than you like, return late in the day.
I’ll be honest: I don’t for a second think that I have the most wisdom to offer when it comes to visiting theme parks. I have only been to Islands of Adventure and the Wizarding World of Harry Potter one time. However, here’s the caveat: I did my research. I read numerous blogs featuring dozens of tips, and I still had issues and obstacles when I got there. So, I am posting purely for the benefit of those people who plan vacations like I do, who will read every blog post on Pinterest hoping to find the best way to seamlessly enjoy their vacation.
