If you go to the Whitley Bay International Figure Skating Camp facebook page, they have just advertised their adult-only workshop during the camp this summer. You can register for this session without registering for the entire camp. There is an on-ice and an off-ice component. It's on 9th August, 12.15-15.15 and it costs £35. I haven't heard anything about a minimum standard for this session but I'll double check when I get my form on Sunday (my coach specifically mentioned it to me and I'm only around Skate UK 7-8 level, presumably she wouldn't have asked me if it was unsuitable).
