You’ll have to ride standby for one of themOne common complaint that I hear about FastPass+ is that someone is not able to grab two popular rides on the same day, such as Avatar Flight of Passage and Na’vi River Journey. That is because they are both Tier One attractions. You’re allowed one choice from Tier One and two from Tier Two in all parks except for the Magic Kingdom. (The Magic Kingdom doesn’t use tiers.) If you already have a Tier One selection, the system is not going to let you nab another for the same day.
