Just to add to what has already been stated. The ride time for coasters is also a lot different than the ride time for other tracked rides such as log flume and splash boats. As the movement of the ride is at a much more leisurely pace, ride times will be quite long for these types of rides. The guests don't usually mind the ride time
ON the ride, but rather, the queue time
waiting for it. This is true for any ride really. You DON'T want to have people saying "I've been waiting in line for ____________ forever (or whatever it is they say, can't remember specifically as I try to avoid it
)"
General rule of thumb, longer the ride, the shorter the queue line should be if you don't want angry peeps. This is also a good thing to remeber if you are playing a scenario where your only source of income is ride tickets and concessions. You may have a killer ride built that everyone wants to take a crack at, but you're not making any money if they are just standing in a queue line for it, even if that line has 250 people in it.
Anyway, I've rambled on long enough. Happy coaster building
