My wife, son, and I traveled to Scotland last July. Too much to see and never enough time, or money. But, I'd suggest seeing the Dunfermline Abbey, about 20 minutes north of Edinburgh. It houses the grave of Robert the Bruce, and it's a wonderful little town. It's, also, the birth place of Andrew Carnegie....see his house and museum. Across from the newer Abbey are the gardens which Carnegie played in as a boy, and then bought later in life, which was returned to the town. It's a wonderful place to hang out and eat lunch. When we took the train there last year, it was 80*..... I loved it, but the locals were dying.

Also, if you make it to Skye, stop by Taliskers Whiskey, which is near the Dunvegan Castle. http://www.scotlandwhisky.com/distil...lands/Talisker

Work your way to Portree for a stop, and and bite to eat.

Have a blast, and prepare to return. The first trip is the learning curve!
