Been here since the 17th. Crowds are typical for the time of year. MK on non party days is significantly busier than party days. If I had to chose then LL for HS is probably the best use of it. The rest of the parks it's ehh...for example yesterday we had LL for HS...we rope dropped and rode tower 3 times, rocking 2, rise millennium, toy story, Mickey's, had lunch...I started booking for Epcot after our second LL and managed to get test track, Remy and soaring for later at Epcot. So overall a fantastic day.
I'll add one more note ..lots of headliners down at park open really sucks and messes up the plan big time. It's been constant during our trip
