Our group (3 people) plans to take 3 train trips from Glasgow, all roundtrip. These are all 7-14 days from now.
Glasgow - Inverness
Glasgow - Edinburgh (day trip)
Glasgow - Ayr (day trip)
(1) What is the best website to buy the tickets? I am based in the U.S., and I would prefer to have the tickets in hand (e-ticket), rather than have to do anything at a train station beforehand, if possible. In the past I seem to remember having to print out tickets at a British rail station, even though I had bought them in advance.
(2) I think it definitely makes sense to buy tickets for the Inverness trip in advance, but Is there any need for the others? I have no idea how full the trains are.
