Traveling from the US to Italy and Germany next month. Purchased a 4-day pass and have already saved my itinerary. I read that it's best not to activate your pass until you actually arrive in Europe since it can't be refunded once activated (just in case something happens last minute and the trip has to be cancelled) but I was wondering how far in advance I should be buying seat reservations?
Some of the trains I've picked require them but most are just recommended. I assume I should not wait until I land in Italy to buy them since the could possibly sell out.
Any suggestions would be appreciated.
