i keep my horse just down the road from normandy (in Ash). Sandhurst draghunt meet in Puttenham which would be just about hackable from you - i have ridden there a couple of times to hack out. There's only one meet there though. Surrey Union also hunt in this area. If your horse is good to load and travel and you're happy to contribute to diesel then it wouldn't be much out of my way to come and get you en route. I've just taken out a subscription to the draghunt so as soon as it thaws out I'll be out with them every week.
Sandhurst also meet at Elstead, Tilford, Camberley etc. My geography of Surrey is not brilliant but I guess they must all be reasonably close if you can find a friend with transport?
