I will be going to Tunbridge Wells from Gerrards Cross whilst my friend will be starting from Wimbledon.
My plan is to meet her at Waterloo having used the Bakerloo from Marylebone. Can someone confirm our routes via Waterloo and Waterloo East are valid on normal Off Peak Day Returns?
Hi, I don't see why not. For your friend's ticket, one of the permitted routes is Wimbledon - Waterloo, walk to Waterloo East, then Waterloo East to TBW.
For your journey, a permitted route is Gerrards Cross-MYB, underground from there to any other London Terminal that is valid for this journey (in this case Charing Cross, Victoria, Waterloo East (Southwark), London Bridge, Cannon Street, Blackfriars, City Thameslink - phew!), then onward train to Tunbridge Wells. Going to Waterloo Underground is perfectly reasonable, and besides you can actually exit (but not re-enter) from the Underground at ANY Zone 1 station (and then walk), if you like. So all perfectly good.
I live in Tunbridge Wells, so do things like this all the time.
