Help me round out my UK road trip in late May

We've got 9 nights in the UK, picking up a rental car in London. We're staying in Bath for 2 nights, then the Cotswolds for 2 nights. This trip is at the end of May.

We have a flight home from Edinburgh 5 nights later. How would you suggest spending the rest of this trip?

I'm thinking we spend one night in Grasmere on the drive up to Scotland - then I'm unsure of our next moves. I figured a night or two in Glencoe, then heading back east towards Edinburgh. We like pubs, nature, music, walking, hiking.

We've been to Edinburgh before, and explored St. Andrews, Inverness, and Drumnadrochit a few years ago. Mainly looking for different ideas and perspectives here. Thank you friends!
