Universal’s Express Pass (UXP) is truly the best. Typically, you’ll wait about only 33% of the posted wait or less. Rarely more than 50%. You can get so much done in a single day!
Don’t skip the shows! In WWOHP my personal favorite is Tales of Beedle the Bard in Diagon Alley.
Also, the Bounre Stuntacular is THE BEST SHOW IN ORLANDO! It’s incredible!
You hadn’t mentioned it, but to go to both parks you need a “park-to-park” ticket. (Park Hopper)
You can take the Hogwarts Express to travel to either park. It’s not a only an attraction with a show, but a shuttle! If the queue is ever more than 40 minutes it’s often better to just walk - even if you have UXP. It’s a slow loading train that gets really busy later in the day.
I’m assuming, since you have UXP that you are staying at a Premier Resort. These offer boats that will take you directly to the parks with little to no waits.
You can get a refillable Coke Freestlye cup and there are self serve locations all over the parks & in every eatery. You can also bring your own bottle and each Freestyle station serves ice & chilled water for free!
UOR does do a number of attractions that may cause motion sickness. Bring your Drimane or other medicines to prevent this!
It may still be warmer weather in October, but go inside either The Three Broomsticks or Leaky Cauldron to get a HOT butterbeer. This is the epitome of what butterbeer is supposed to be.
Frozen butterbeer is refreshing & a crowd favorite. However, IMHO, nothing beats that warm toffee & marshmallow goodness of HOT butterbeer!
Other “don’t miss” attractions outside of WWOHP - Revenge of the Mummy, The Adventures of Spiderman, Jurassic Park River Adventure and the Raptor Encounter character meeting…
If you like tator tots with meat & cheese then stop by the Green Eggs & Ham tots QS. My favorite QS in all of UOR!
I prefer eating at Three Broomsticks more than Leaky Cauldron. LC serves more traditional British food while 3B serves ribs & chicken
Be aware that this is Halloween Horror Nights season and Universal Studios will close at 5pm Wed. - Sun. for the event. If you are going on one of those days prioritize USF / Diagon Alley to start your day.
If you can stay until after sunset, Hagrid’s is simply “epic” after dark. It was designed to be ridden that way as there are no lights out there expect on your motorbike. Try to get in queue right before IOA closes as the last ride.
There are many good eateries in CityWalk and the hotels. Let us know your likes / dislikes & we can steer you to the best options. I have found that the Premier hotels have the best restaurants!
I can talk about Universal all day, so ask any questions!!
