The Attraction CMs try to keep FP guests' wait times to the standard FP wait times. Two weeks ago, Safari in AK had been down due to animals in the roadway.
Standby was backed up but we entered the FP line and were on the ride in less than 15 minutes. Standby guests were complaining they had been in line for 2 hours and watched at least 100 FP guests ride before them as they were standing in Standby. That's the perk of having a FP booked weeks in advance.
