Hello! I'm looking at the cheapest possible way to route a trip. A friend is visiting Egham, and then going to London the next day to catch the Eurostar. I was thinking of buying an open/anytime return from Havant to London Waterloo--travel from Havant to Egham, spend the night in Egham, and complete the outbound leg to Waterloo the next day. Since this route is a little out of the way (given that Havant is on the direct London main line) would this be feasible? And would the overnight break of journey be acceptable without eating into the return ticket for a week or so later? Thank you so much!
