That's fantastic!!! I don't live in the UK, so may or may not have signed the petition (I don't recall).
There is a similar fight going on at a rink in Portland Oregon. The rink is in a shopping mall, and rather than closing it, they're making it too small to be useable (for anything other than public/group lessons). 23inmyhead, if you, or anyone else on here for that matter, have time and energy, your experience and insights would, I imagine, be very welcome. I'm not involved in that situation, so I can't say for sure....just putting it on your radar.
Here's their facebook page:

Congratulations on your success!
