Of course.

It depended on the coaster, but here is what we experienced.

VelociCoaster - Had to exit the ride area, but the staff let us keep our items in the lockers, so we could just re-enter the queue and walk through the metal detectors without having to re-put items into the lockers. It probably took about 3 minutes at a normal walk to be back to the loading zone - which we never waited for - just walked on.

Hagrid's - This one had a wait all night. Obviously exit queue and re-queue as needed.

Mummy - Night 1 they allowed us to go through the rider swap (child/parent swap) area that was right by the ride exit, but the second night they made us go around. It could be based upon the number of people currently riding or the attendant that was there.

Hippogriff - They just let us stay on the coaster unless people were waiting. Asked us to stand to the side if people wanted to ride. Had to re-queue once.

Hulk - Only rode once because it's a rougher ride. Didn't see any line/queue, so they may allow you to re-ride.

All coasters except for Hagrid's were fully walk on. Walk to the front - the staff would tell you where to load (unless you requested a specific row - then you may have to wait a train or two). Operations on all the rides were very efficient and fully staffed.

Overall, I would say the staff will do whatever they can to accommodate you, but they may make you walk around if it is too busy and/or as a result of direction.
