Hello, I am traveling to London in early May, arriving early on a Friday morning. I am meeting a friend, who will be arriving the night before and I will meet her at our hotel on Friday. She has been to London before, but I haven't. Because she's been there before, we were thinking of just spending a couple of days in London and then renting a car and driving up into Scotland, or possibly taking the train. So, I have a few questions (I know this is the London forum, but I hope you'll permit me to ask some quasi-London questions):
1. Is this even a realistic idea, or will we regret leaving London to go north for such a short time?
2. Assuming that this were feasible, would we be better off renting a car, or taking the train to Scotland?
3. Where would be the best place to spend a couple of nights in Scotland to be able to see a few castles and interesting sites?
4. Should we just stay in London and take day-trips out to see castles? Which castles would be easily accessible?
