I'll be in Scotland last of August- first of September. My first experience driving on the left was picking up a rental car at the Dublin airport this past September for 2 weeks driving in Ireland. Not too bad since Dublin airport isn't huge.
For this Scotland trip I'm flying into Edinburgh. I considered taking the train to Glasgow and picking up a car at the Glasgow airport, but think I'd rather spend more time in the countryside and skip Glasgow.
For someone who doesn't spend a lot of time driving on the left, is there a big difference in difficulty getting out of either the Glasgow or Edinburgh airports?
