hopefully, DHS is up next to recieve a refresh.
MK and EPCOT have both recieved some quality things in recent years, and DAK is chugging a long just fine (despite the fact that people are adamant it's only a half day park. it is if you're only there for rides, but it has so much to offer in terms of things to see. people are, quite frankly, boring).
DHS has the least amount of things to do, especially for smaller children after all the stage shows close for the day. only two of the nine rides in the park don't have height requirements (and therefore allow lap-sitting and have no restraints), and one of which experiences frequent downtimes, not to mention both are subject to long waits.
the park really NEEDS more rides, especially things along the lines of classic fantasyland dark rides or an omnimover; things with small or no height requirement that probably won't require a restraint. another thrill ride would be a welcome addition, but the park needs something with a high guest-per-hour count that can help devour crowds when ROTR, MMRR, and slinky dog inevitably experience a downtime. another coaster wouldn't hurt either.
most of my ride expansion ideas pertain to SW:GE, which can, unfortunately, only fit one more attraction unless they wanted to move some things around (like moving the Grand Ave. entrance up, ROTR taking muppetvision's extended queue and redirecting its' entrance). a podrace duelling coaster, a speederbike chase coaster or a boatride through batuu's alien scenery would do well. perhaps a peoplemover-esque attraction would have been good as well, but it's too late in the game to install something like that.
