When is your trip and are can you use single rider (not sure if you're travelling with little ones)? But I can tell you we have gone (DD and I) the last 3 years during the verrry busy President's week. We always rope dropped the EMH park and hit many rides multiple times in about 2-3 hours. At DHS we headed straight for Toy Story, rode it, then to Tower of Terror and Rock N Roller Coaster (more than once, using single rider). We were done and used some time for Great Movie Ride if I'm remembering correctly, before heading out to walk over to Beaches N Cream for late breakfast/early lunch at 11:30 where they weren't even open yet we had so much time to spare. Even during a very busy week those EMH really work in your favor. We also used FP on other days for those rides later in the day after going to whatever park had EMH. We only ever buy park hoppers, to that works in our favor too. As for AK, if you go there at rope drop (as we did also on it's EMH days) you can easily ride Everest 4, 5 even 6 times or until you are sick of it over and over as walk on or single rider. Line is so short they don't open single rider right away. We rode it twice before single rider opened. Most of our family thinks we are crazy for the way we "hit the parks" but we pack in all we can and maximize the time by doing Rope Drop, EMH, taking a few hour mid day pool/resort/nap break, then FP another park later in the day until park close. Some days we even hit a third or fourth park depending on park hours during our stay. Have fun!
