13 nights in Scotland itinerary help :)

I have been working on an itinerary for a scotland trip that will take place in late September - a little bit of October. We are a group of 4 30 year olds and my 65 year old parents (relatively fit). We definitely want to spend time in the highlands and in Edinburgh, it’s the no car piece I’m struggling with. My mom is very anxious about us driving on the left side of the road and is very against getting a rental car. We are willing to pay for drivers for certain areas, but we’d like to avoid bus tours if possible.

Our main focus is dramatic landscapes, castles, picturesque villages with high quality local shops and art, and cultural experiences. We are ok with some shorter hikes, but we are trying to go places with alternatives if the weather ends up being terrible

We plan on flying into Edinburgh and staying there for 5 nights and taking a day trip to Stirling

At least 3 nights in Skye (we plan on hiring a driver to take us to Skye and stop at locations on the way in Glencoe) and we will hire a day taxi to take us places in Skye

This next piece I’m struggling with:

- maybe 3 nights in Oban followed by 2 nights in Glasgow? Or maybe add a night to Oban or Skye and then just one night in the final city before flying out?

- would one full day in Oban without a car seem like too much? I was thinking for the second day hiring a guide to take us around Glen of Kilmartin or Mull

Other options we’re considering instead of Oban

- Inverness - seems like it gets a lot of mixed reviews

- Pitolchry

- any place I’m missing?
