Absolutely!!!
At MK we arrived at rope drop and got the following done by 10am
-BTMR twice
-POTC
-Jungle Cruise
-Haunted Mansion
And that was with walking slowly and enjoying the scenery since it was our first day
The second MK day we did
-Space twice
-Astro Orbiter
-Buzz twice
-Pooh
before 10am
Epcot first day (before 10am)
-Soarin' twice (walk on both times)
-LWTL
Epcot second day (before 10am)
-Test Track
-Soarin'
-Nemo
HS (before 10am)
-RNRC
-TOT twice
-Star Tours
I hope that's helpful! Arriving at rope drop is definitely still advantageous!!! All of the mentioned rides were basically walk-ons, 5-10 minute wait at the MOST
