Just booked a London flight for a trip beginning at the tail end of September through Oct 12. Thinking about starting out by going to Edinburgh for a few days. What are the advantages/disadvantages of going from London to Edinburgh by train or by plane? Cost? Time? Is the time saved by flying at least partially balanced by the time and hassle of getting to and from airports?
I like autumn English weather, and I'm guessing Edinburgh's will be a bit chillier. Any chance that I could run into a stretch of really cold -- with high temps in the 30's F. -- weather?
