Recommendations please. I've had a couple of years of upheaval and the summer has vanished in another house moving farce

, so I'm cross that my planned "back to the saddle" programme with my local classical instructor got derailed after lesson two. Partly I think its because she has a set curriculum and its very much about getting the horse to do things

, and right now I feel I need to focus on my balance and position. My original "education" was a long time ago and very regimental, so I need to unlearn things and replace them.
To kick start this I'd like to find somewhere I can go for a little break and have 2 or 3 days beginning again from the absolute beginning but with really good enabling teaching, preferably on the lunge. As everywhere tends to be far it needs to be intensive enough to make it worth the journey and time away, but not leave me a wreck and unable to keep the momentum! Ideally I'd also like to hack out as well as have a daily lesson.
Any ideas please?
