The ride ops aren't "lazy" for not letting you up. There's a reason they don't want people just standing in line on that bridge, and that reason is because people will throw things
off that bridge. By letting them up a few trainloads at a time, people are more worried about getting into the station and on the coaster than they are about pelting John Q. Guest with M&Ms. Please, don't just start putting blame on the staff and calling ops "lazy" when you don't have enough knowledge to make an informed opinion.
And yes. Definitely go on a weekday, if at all possible. Try to check Kennywood.com for days that may be a nationality day or a big group picnic (Girl Scout Day, Cheerleader Day [though you might
want to go to that one ;)], etc.) Those are general rules of thumb I use...
