Another thanksgiving week person here - I've been obsessively checking wait times and reading trip reports and watching
YouTube vloggers - and from all accounts (including weekends) and holiday weekends (Labor Day) - it's going to look like a lot of lines are happening, and the wait times will LOOK high....but they all say the same thing "posted is less than actual".
A few other things i've heard over and over again -
Unless you're going to HS, there's no need to "rope drop" and avoiding the early morning crowding may work in your favor
HS - get there as early as you are able to, rope drop Runaway Railway (they usually start it before the park officially opens) and by the time you get off - if timed correctly - you should be able to do the 10am boarding group drop for Rise of the Resistance - and save the headliners for the end of the day if the wait times are bugging you out - Slinky dog, Tower of terror, they usually start winding down at the end.
Even if they are at "capacity" which most likely they will be, it still won't be as crowded as it was in previous years. They don't have a bunch of things that would normally take people out of lines - like live shows and parades etc - so that's not helping - but I don't think it matters what park you pick or what day. Weekends are always busier.
The Park Pass availability calendar showed that resort guests and theme park tickets passes are "sold out" of pass availability for Hollywood Studios on most days during Thanksgiving week so that should give you some idea. I'm SURE they will extend hours though. Either way - it'll be fun. Just different.
