We typically do 18 to 22 rides in one day, rarely waiting more than 15 minutes and usually less than that. This is accomplished by:
1. Visiting on slower days (Friday before Labor Day, mid-week in February, Thurs/Friday in mid-April)
2. Rope dropping
3. Lightning lanes
4. Experience that allows us to eyeball the lines and know whether the posted times are accurate. Last Friday, Rise had a posted wait time of 45 minutes but the queue wasn't even sticking out of the caves. We got in line and waited 15 minutes standby.
Happy to discuss strategy in more detail, but the basic answer is that you can pretty much walk onto Space or Indy right out of the gates. Space will be at least a half hour, often more, a half-hour after opening. Indy will likely stay close to walk on for the first hour. On slower days, Big Thunder will typically remain 15 minutes or less for the first hour. Outside of rope dropping and/or Lightning Lanes, my sense is these are typical wait times on a slower day, but you can absolutely beat these times with strategy/paying more $.
Indy: 25-50 minutes
Pirates: 10-20 minutes
Jungle Cruise: 5-25 minutes
Big Thunder: 15-30 minutes
Haunted Mansion: 15-30 minutes but currently walk-on due to virtual queue
Space: 30-60 minutes
Mickey & Minnie's RR: 10-45 minutes
Roger Rabbit: (I would only ride this one early in the morning or with
Lightning Lane) 20-50 minutes
Dumbo: 10-20 minutes
Mr. Toad: 10-15 minutes
Matterhorn: 20-45 minutes
Rise: 25-50 minutes
Smuggler's Run: 5-30 minutes
Anyway, the lowest possible times for the big rides are basically: no wait at all! But this is never guaranteed, even with lightning lanes. Your best strategy for minimizing waits is to show up at opening and use lightning lanes as the park gets busier toward midday.
