Hi Everyone

I followed the thread of Bill Schwab's trip to Scotlands West coast with great interest and am about to book a flight to have a four day break in and around that area, Hopfully the first week in March. I just have a few questions.
What is the best airport to fly to, Glasgow or Edinburgh? And how long can I expect the journey from the airport to be? Also, would I be better off booking a place to stay before I leave home or stay as I find?

Your help will be much appreciated.
