When using FastPass+ in the parks, it is always recommended to not book any fastpasses in the first 2 hours of the day. The lines in the park are a lot lighter at this time and the Fastpass+ is usually not needed. It is best to use FastPass+ later in the day when the crowds arrive and lines began to grow long. FastPass+ in Epcot has a tiered system. You are only allowed to pick one attraction from the first tier, and two from the 2nd tier. The following is a list of the rides that you should get FastPass+ for in Epcot in order of longest wait times:
Tier One:
Soarin
Test Track
Mission Space
Tier Two:
Spaceship Earth
Meet Disney Pals at Character Spot
The Seas with Nemo and Friends
The only two rides at Epcot that really need a fastpass are Soarin and Test Track, but unfortunately, you only get to pick one of them. My advice is to choose one of them and ride the other one immediately at park opening. Mission Space is probably the third best ride in the park in most people’s opinion, but it is a very distant third. (As of the writing of this post, Soarin is currently closed for a long refurbishment. When it returns, the video will change from Soarin over California to Soarin over the World. There will also be a third theatre added to the attraction.)
The second tier at this park is a big drop off from the first. Spaceship Earth is definitely worth a ride if you have never rode it before, but my family only rides it once every 4 or 5 trips. It’s not a bad ride, but for me it is not worth waiting more than 5 minutes. Since it is located in the Epcot ball and very front and center, the line there tends to be very long. I can only imagine that first time visitors see this as the first ride when they enter the park and think it is a must do since it is the icon of the park. I would recommend riding it if there is no wait or you have a fastpass, but do not feel bad if you decide to skip it. I would normally not suggest a Character Meet for a fastpass, but there is really nothing else here to use your fastpass on in this park. You have an extra fastpass selection; you may as well use it somewhere. The Seas with Nemo rarely has any weight at all, but again, if you have nothing else to use your fast pass selection on, you may as well use it here.
