I have some friends who seem to favour Stockland Lovell. I am about 1/2 an hour from there too as it's on the outskirts of Bridgwater, on the Minehead road.
I have not been there yet, but I went to Pontispool early this year to photograph an HT event, and it looked like an interesting place to ride.
I have been to both on camps not much in it. Prefer the stables at Pontispool but human accommodation is not very good. At SLM the human accommodation is very good. I also think the instructors can sometimes be better at Pontispool. Food is very good at both!!
There is not much in the XC either I guess SLM has more variety but last time I went they had put away all the big stuff and more challenging fences and was more set up for PC.
