We'll fly into Southampton from Dublin on June 1, and sail out on June 3. Since time is limited,but we're close to London, we plan to go up to London and use one of the Hop-On/Off Buses to see at least a bit of London.
After checking alternatives, National Express Coach seems the best bet, but I'm left with a couple of questions not answered by their website-
We're both over 60, so eliible for the senior discount, even tho not UK residents - correct? (the only benefit of getting older)
We can either book return tickets or "open" return. I'm inclined to the "open" return for flexibility, but not sure how flexible it really is or how to use - can I book the same day, just before boarding, etc.? My concern is that if we miss a booked return, the ticket is void and we have to purchase new tickets at full fare . For ease of mind, should we just book the return for the latest possible time and leave it at that?
And of course any other advice or insight will begreatly appreciated.
