A few of my friends and I are planning a trip to Scotland in January. We are all college students, so travelling over winter break is ideal for us. We are too young to hire a car so we planned on using a Britrail/Scotrail pass. As it stands now, we have found extremely inexpensive flights to London. From what I have found, the Britrail pass is essentially the same price as a Scotrail pass. Intuitively, we would be saving money by travelling from London to Edinburgh, however, we would miss out on some of the discounts on bus fares offered with the ScotRail pass. Since we are all under 25, we can't hire a car.
First of all, are we crazy for flying into London? Second, what other transportation costs will we incur during our trip? How close are the trains to attractions such as Doune Castle, or Loch Lomond, or Glencoe for example? Our Itinerary is not entirely set yet, but we would like to know more about transportation in Scotland before we set our locations. Any information is greatly appreciated.
