Epcot doesnt have many scary rides. fastpasses free but you only get a limited amount. Single rider lines on many rides.Islands of adventure tons of scary rides. 50$ fast passes. only some rides have single rider.. few.single rider is usually about 1/2 the time of the usual wait time
I just returned from those two parks. Epcot is much busier than Islands but only an extra 5-10 minutes wait. You re probably going to be expecting about 30 minute lines wait compared to the 10 minutes I did.Epcot offers fast passes for free while Universal Orlando you have to pay for them. Some rides in Epcot (I think) don t have single riders. It would be best to do single rider for Islands. You are basically doing the same amount as Express pass. If you do decide to do express pass for only Islands will cost you $19.99 + tax. I wouldn t do it because you will be the only one. Single riders wait no more than 15-20 minutes.There isn t many scary rides to do in Epcot. Only Mission Space but they even have a Mild version for you to do with your family and the line is half as long as the extreme one. Try doing Soarin early it isn t scary but the lines are always full 45 minutes when I went. test Track isn t scary and good for the family. Epcot only has a few rides. With your maingate ticket you go to the front of the ride and there will be this machine to get fast passes and it prints one out for you with the times for you to return.Islands has the Hulk, Dueling Dragons, and Doctor s Doom s Fearfall (i think that s the name). DD is usually the shortest waiting time of the three. There was no wait time. Dueling Dragons has a LONG queue line but you basically just jump on when you get to the coasters. The hulk is a bit busier of the three even with express pass, but the waiting time isn t really long. It was 5 minutes on a Wednesday and 10 on a Saturday. You can get your express pass for for the park online or at the gate.Good luck and have fun!!!
