I suppose you should just be happy it didn't go up by more as rumour was originally that it was going to be double....
The parking problems are not UWS's fault per se - it's another company that runs the stuff now.
I called the uni to find out what was happening with them at the end of last year cause i went on ipay to buy one and it wasn't there, and the staff i spoke to also had the same gripes we do about the delays and price. So for a change, UWS is sort of, in a way, on our side too.
If cost is a really big problem and you need to drive to get to uni, you can always park off campus and walk a bit to campus. There's a few side streets around some of the campuses that are usually basically empty that you can park in and walk over not too far.
