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 Hollywood Studios 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 the Hollywood Studios in order of longest wait times:
Tier One:
Toy Story Mania
Rock’n’ Roller Coaster
Tier Two:
The Twilight Zone Tower of Terror
Star Tours
Toy Story Mania is the ride that everyone runs to as soon as the park opens. Fastpass for this ride must be booked at least 30 days out from your trip as it is very popular. The general rule of now booking a fastpass in the first two hours can be broken if that is the only time that is available.
Rock’n’Roller Coaster is definitely a ride worthy of a fastpass, but given the tier structure at Hollywood Studios, it is hard to choose Rock’n’Roller coaster over Toy Story Mania. While Toy Story Mania usually has a line immediately when the park opens, you can generally ride Rock’n’Roller Coaster in the first few hours of the day with a relatively small wait time.
The Twilight Zone Tower of Terror and Star Tours are the only two rides in tier two that are worthy of a fastpass. As a matter of fact, they are the only two rides in the second tier. All other attractions in tier two are shows. It is highly advisable to avoid shows for fastpass reservations, as you will generally be sitting or standing right next to someone that did not use a fastpass. The only time this may not be true is during extremely busy times a year when it might not be possible for all park guests to enter a show. It is only these few times a year that shows fill up all seats in the theatre.
After using all 3 fastpasses for the day, it is advisable to first check to see if there is a fastpass available for rock’n’roller. They are usually not available, but it is always worth a try. Next I would try to secure a fastpass for Fantasmic. During busier times of year, there are normally two showings for Fantasmic in the evening. The second showing is usually not full and it is advisable to attend that showing if possible. If you would like to see the first showing of Fantasmic, it is helpful to have a fastpass to make sure you can get into the theatre and get a seat. Without a fastpass, the first showing will frequently fill up and the seats remaining for non-fastpass guests are extremely limited and sometimes it is standing room only.
