That plan was an expedition, with so much time spent moving, there was not enough time to see anything. I've simplified:

Border Abbeys for a day.
Lake District for a few days.
Attend the meet.
Islay for a few days (skipping Arran?).
Isle of Skye for a bunch of days.

Trains will get me to the locations, and I'm hoping local bus and shuttle service will get me around once I'm there. Hiring a car last year was great, but seems inefficient with ferries involved. Heck, maybe just hire a bike and ride around...

Thanks again for the tips and great pictures. The plan is shaping up.
