Scottish Highlands Vacation -- What would you bring?

I'll be heading to Scotland for a ~2 week vacation. My wife and I will be taking a train tour through the Highlands, starting in Glasgow, hitting Loch Ness and the Isle of Skye before heading to Inverness and ending in Edinburgh. We'll then be spending several days in Edinburgh before heading back home.

Normally I'd try to keep my camera gear to a minimum on a trip like this, but I'm hoping there may be some landscape opportunities that would have me wishing I'd brought just a bit more gear.

I'm not going to list my gear, but I'd like to hear from some other photographers what they would bring. Would you stick to a minimalist set up or would you bring some longer lenses to cover your bases?

TIA!
