To be fair, Vale Park hasn't changed all that much. It's still a great spot to stroll around and the cafe is very popular (just try getting a table outside when the weather is nice). I very seldom see litter or dog dirt lying around, inspite of how many dog walkers visit the park.
It's a gem of a place, and the little gallery inside Vale House and the local History
info they provide all contribute to the popularity of the place. You'd be surprised how many people still go to hear bands at the bandstand. http://www.flickr.com/photos/wonkyknee/3635748434/
