Hey, thanks Lee, that's a great help and a great idea.
Like I said Windermere was picked because it's the easiest train access, it's just a basepoint, leave my stuff there, sleep, shower etc, I never intended to spend 4 days in the same place it's just convenient. A walk to Orrest Head and that's pretty much it for Windermere, I plan to check out as many places as possible except I'm relying on buses. And you're right Great Langdale is only a 30 min bus ride so your recommendation is even better, to be fair most of the places I want to head to are an hour bus ride which really isn't bad at all, still get to ramble which is the whole reason for the trip.
Appreciate all your help and I'll look into all the locations/routes etc. Looking forward to getting out there
