We'll be driving from Inverness area (actually staying in Nairn, a bit east of Inverness) to St Andrews on a Monday in May. The inland route through Pitlochry seems to be the most popular, but we are wondering about the coastal route via Aberdeen.
One point of interest would be the golf course development Donald Trump has been building near Aberdeen -- not to play golf but just to drive by, if it's not too far out of the way.
However, we're much more interested in arriving in St Andrews not too exhausted. Which route would be better for traveling the distance in a single day?
