We were just there July 22- July 31, so 9 nights. This was our 5th trip this time of year (Late July, Early August) going back to 2016.
We did:
- MK 3 times
- HS 2 times
- EP 2 times
- AK 1 time
- Typhoon Lagoon 1 time
The parks did not feel overly busy, and probably the least crowded summer visit. I mean, there are always a lot of people in the parks so they don't ever feel "empty" in the summer, but this one never felt crowded either.
We've had late September visits more crowded in the peak years of Free Dining, like 2013-2015, that actually got up into the crowd levels of 7 - 9.
Touring plans had forecasted this trip to be 4's - 7's but looking back now they adjusted the actuals down to 2's to 6's depending on the day. I would say it actually probably felt more like 4-6 out of 10. We've been using touring plans since 2010 and I remember those 2's in 2010 were like ghost towns in the morning compared to now. Nothing felt as low as a 2 during this trip.
Either way, crowds have never been the issue in the summer for us. Just prepare for the heat (we take afternoon breaks). For us, we wouldn't visit without a "skip the line system", so we bought LLMP for every day except AK. I
loathe paying for it, but If we didn't have LLMP we would have gotten
FAR less enjoyment out of our visit.
We do refuse to pay for ILL so we did stand in line for those, but that's just one per park and typically was anywhere from 30-80 minutes for ROTR, FOP, TRON, and Guardians.
