The "title" says it all. Our trip starts in mid-September and ends in early October. When I can book rail tickets, knowing whether the Gatwick airport train station has a booth where we can turn in the form and our photos to get the Two Together pass, will be helpful. And, are the kiosks manned Saturdays and Sundays (I think we arrive on a Saturday)?
We are flying into (and out of) Gatwick. Since we arrive at about noon, we thought we might spend a night in Brighton before catching another train on to Bath. (While we will also be renting cars or flying within the UK for parts of our 3 & 1/2 week trip, we also plan to take the train from York to Cambridge and then from there back to London.)
