I haven't skated at many, Sunderland was great but they've closed it down now. Whitley Bay is fine but only been a few times. Skated a lot at Blackpool some years ago but found it quite small. I don't fancy Doncaster after reading the posts on here but am going over to try Sheffield during the holidays hopefully.
Bradford seems tacky, its an old building and it hasn't changed much since I was there as a teenager lol but its quite large and airy so it will do for me and I'm biased anyway!
