Most of the time the queue doesn't extend onto the ramp, but from what I can remember, there are two switchback areas inside the station.
The arrows point to roughly where these areas are. After the ramp is one set of switchbacks, then there's an outside portion of the queue and finally the last set and train loading queue.
The ride also only loads 4 people per car, and there is almost always 3 waiting in the station while the rest are somewhere on the track.
Many people want bigger and better thrills, and there are coasters for that, but RS is not necessarily one of them. There's a reason why HP rates RS a 3 (for "moderate thrill ride"). Also, sometimes people are already coming from the other water attractions, and it can get chilly waiting in line for Rollersoaker in particular, so that detracts from the ride experience before the ride even starts.
I enjoy Rollersoaker because of its novelty. There's plenty of rides with more thrills at HP, but there literally aren't many rides like RS itself.
Proslide Rockets are almost always suspended, and so there can be more than just a slide placed in this area. So far, I think Hersheypark has all the waterpark basics covered, from a kiddie area and water structure to lazy river and wave pool, plus tube slides in general. The only other things I can think of are hot tubs and generic pools.
Perhaps other types of water rides like a speed slide or Proslide rocket can be placed somewhere among these attractions.
