Or go rogue and get a house in torridon for a fortnight?
I'm sure you're already aware but Targassonne is a long drive from Font at ~9/10hrs.... I really like and rate it but I wouldn't recommend leaving font and spending a full day driving to it. Personally, I'd just stay in font. People seem to enjoy and have good trips there but I struggle to comprehend how solely from a skin perspective - there's generally a lot of crimping and the rock's , well, rock hard, large grained granite. I usually find my skin's pretty knackered and crimped out after just one decent session there.
