I seriously consdiered doing this - combining vacation with a retreat to learn to spin and come home with a louet wheel. Then I started to look at the cost - I can get the basic louet they are talking about for around $200 but if you don't have your own wheel they will charge you $400 for that basic louet.
Anyway not knowing what wheel would be best or how to spin etc, I did some more research and found this woman far closer to home who will do one on one tuition at a very reasonable price and she will do adaptations and repairs to wheels. So I'm going with her on 5th August.
I still hanker after this retreat it does seem fun but with flight costs on top I'd need to learn to spin a bit first and buy a wheel before doing it!
