I'm not sure but if you are wanting to go to a course and are worried about it being back in time, why don't you join on the day? They usually give you a temporary card so you can go to others before your full membership pack comes back. The ones I have been to have all been pretty reasonable about it
Went to Burton Hastings a couple of weeks ago with my daughter (she was riding I took the dog!) Nice course, small water jump, 1st section small jumps, 2nd a bit bigger , 3rd about 3' 6'' but can go around all fences if you want to. Ground was a bit hard in places to jump anyway so did need to walk/trot alot of it but my daughter had a good ride anyway, about 6 miles. Ignore the 'road closed' sign at the start of the drive if you have a trailer, only applies to big lorries, but may have gone now as the track had just been resurfaced when we went.
We will be taking the lorry so hopefully the road will be open by the time we go. I think I'll probably be going round most of the jumps except the teeny weeny ones
