Hi!
I am going to travel from Sweden to Germany and the UK in December-January. It seems like an Interrail pass will provide more flexibility and less costs than booking with the separate train lines, but I have a few concerns regarding this. First, I would still have to book seat reservations to be sure to be allowed on the train (in most cases, especially from Germany to the UK?) Second, seat reservation tickets for UK trains will be posted per mail which means I cannot be spontaneous about the exact date, and I have to book and receive these tickets before I leave for Germany? This seems to make it rather inflexible. (And I read about a nightmare scenario where one customer had to buy a full price UK Eurostar ticket despite having an Interrail pass!)
Then a few other questions. Can I expect discounts on most regional buses? Would I need to buy a completely new pass / separate tickets if I notice that the period of time / number of travel days won't be enough? Does December-January usually count as peak season (considering Xmas and New Years). (How far in advance would I need to book each trip)?
I hope you can help me.
Thanks, Felicia
