You can buy an express pass for Halloween Horror Nights at Universal Studios Florida to ensure that you'll get to see all the haunted houses by closing time. However, if you don't want to spend the extra money, you'll need a good touring plan.
Even though I have express, I pride myself on seeing how many houses I can do without it each night. Here's my touring plan to help you get through them as expediently as possible:
1) Either get a day ticket and stay in the park after it closes (they'll let you stay in a holding pen) or be one of the first people at the front gate. If you stay in the park, you can either wait by Finnegan's or the kids' area. I always choose the latter because it's less crowded. Also, they start letting people in the front gates early, and most of them head to the sound stages, which is where the people from the Finnegan's pen go. It's stays less crowded longer in the kids' zone area.
If you have to come in via the front gates, turn right and head toward the kids' zone rather than going straight and doing the sound stages.
2) Do The Walking Dead, then La Llorona, then go to Havoc. This might sound counter-intuitive because The Walking Dead exits at the entrance to La Llorona, which then exits at the entrance to Afterlife. However, Afterlife opens at 6:30, so it won't be open yet if you use my touring plan. Havoc opens at 6, so instead of waiting in a pre-opening line with all the sheep, you'll stroll into Havoc with no wait.
3) Return to Afterlife or go to the sound stages. It's a bit of a toss-up on what to do next. The sound stages get the biggest lines because they're the first ones people see, and they're all based on popular intellectual properties. Thus I usually see how bad their lines are and do Afterlife later in the night.
The lines for An American Werewolf in London and Evil Dead build a little slower because they're the farthest from the front gate. However, Evil Dead doesn't open until 6:30, so it might not be open yet when you get there. If not, do Werewolf, then Evil Dead.
If you follow those three steps, you should have five of the eight houses done (or four if you went back to Afterlife, after which you should head to the sound stages, starting with Werewolf and Evil Dead). At this point the lines will be building, so be prepared for waits on the last three houses. However, you'll have plenty of time to get them done, as well as to see Bill and Ted's Halloween Adventure and stroll through the scare zones (I don't recommend Rocky Horror because of the limits placed on the call-backs).
A few quick notes:
- The rides rarely have long lines during Halloween Horror Nights because everyone is focusing on the haunted houses. Ride them if you like, although I recommend doing all the houses first so you don't waste valuable time.
- Bill and Ted is great to do when your feet are aching after rushing through as many houses as possible and you need a rest. Don't do it early in the night or you'll kill valuable short-line time for the houses.
- Repeat Havoc after dark if the line is short enough. It's a totally different experience after dark because it's in the Disaster queue line, which means there's a lot of light during the day. That's great for seeing the train wreck detail, while night is more of a traditional experience.
I use these tips myself, so I know they work. Follow them and have the best possible experience.
