So I have a trip July 9th. The trip reports lately are terrifying as a parent with young kids. I can't cancel the trip without losing a significant amount of nonrefundable things, but I'm currently researching going to Universal and some of the other parks that have line-skip alternatives (or just aren't as super crowded for kiddie rides). Annoying that I'm going to be staying at a Disney Deluxe resort and not really doing the Disney parks, but whatever I guess. Great Job Disney!
We booked our trips knowing there was no FastPass and we explained to our kids (ages 8 and 5) that, if they really wanted to go, they would have to wait in line.
We were just there for 9 days with 2 kids (ages 8 and almost 6) and came home Thursday evening (the day before yesterday). We found the crowds to be fine on this trip, as long as you got there early (especially on weekends). They increased capacity (and changed mask rules) right in the middle of this last trip and it was still okay in terms of crowds but we don’t spend all day in the parks. We go early, leave after an early lunch, and head back in the evening.
We went to Epcot Sunday and, in the first hour, had ridden Test Track once and Frozen twice in a row. Nemo had no wait even though the app showed a 25 minute wait. Same for Figment and Three Caballeros.
At MK, we spaced out our time because we had three days there. When we went in the afternoon (around 4:30), crowds were incredibly low compared to the earlier times (even on Friday). These are the longest waits for rides we had across all three days at MK:
-Small World was a 10 minute wait (posted time 30 minutes)
-Peter Pan was a 15 minute wait (posted time 45 minutes)
-Teacups were walk on (posted time 15 minutes)
-Pooh was a walk on (posted time 25 minutes)
-Dumbo was a 5 minute wait (posted time 20 minutes)
-Little Mermaid was a walk on (posted time 25 minutes)
-Buzz was a 5 minute wait (posted time 25 minutes)
-People Mover was a 5 minute wait (posted time 20 minutes)
-Mine Train was a 20 minute wait (posted time 60 minutes)
-Thunder Mountain was a 10 minute wait (posted time 25 minutes)
-Splash Mountain was a 30 minute wait (posted time 70 minutes)
-Haunted Mansion was a 10 minute wait (posted time 30 minutes)
-Flying Carpets were a 10 minute wait (posted time 30 minutes)
Hollywood Studios was fine. We had waits of:
-15 minutes for MMRR (posted wait 30 minutes)
-5 minutes for Swirling Saucers (posted wait 15 minutes)
-10 minutes for Toy Story Mania (posted wait 25 minutes)
-20-30 minutes each time we rode Slinky Dog (we rode it four times across two days; posted wait each time was 70-75 minutes)
-85 minutes for Tower of Terror (completely accurate wait time for when we rode it)
-25 minutes for Millenium Falcon (posted wait 80 minutes)
At Animal Kingdom (where the longest waits were on the weekend days for us):
-Navi River was a 10 minute wait (posted time was 30 minutes)
-Safari was 20 minutes one of three times we rode it across two days (posted wait time of 40 minutes that one time, walked on other two times)
-Kali River Rapids was walk on both days (posted time was 25 mini items)
-Flying Dinos were walk on both times (posted wait was 20 minutes)
-Dinosaur was 20 minutes both times (posted wait was 45 minutes)
I hope that helps ease some of your concern.
