Thanks again all, paid the £51.40 in the end.
Meeting an old schoolfriend from Plymouth who's living down there now, we're visiting a new(ish) craft ale Tap room which comes highly recommended, will report back!
A decent trip - Taplow to Farringdon on the Elizabeth Line and then Southern to Hassocks yesterday - on time to the minute - 12 carriage train so plenty of room even though it was busy - same trip in reverse today with no problems - Southern apparently don't have crew shortage issues on Sundays, I wonder what they do differently?
Discovered a couple of new bars and aforementioned Tap room which was excellent - also invited to play "Toad in the Hole" which apparently is a traditional Sussex pub game, and even saw some Morris dancing!
(I took part in the former, but not the latter!!!)
