Ummm..... Groupsave only works in multiples of 3 or 4 passengers. You can't put 5 on one ticket.
3 for the price of two or, the more desirable, 4 for the price of 2.
Although I already have a ticket, I do have a network rail card which could plausibly be deployed on the day IYSWIM.
EDIT - Railcard cannot be used in conjunction with Groupsave.
I was going to buy tickets for 5 people and share the overall cost. I thought it would be fairer that way. But maybe we can use your railcard to get the one non-group save ticket, which would presumeably save a little cash. Thanks for the offer.
User10571, thanks also for updating the route to take us to the Compasses at Gomshall. People should be able to download this here.

Now the numbers are nearly finalised (still waiting confirmation from Davy Walnuts) I will give the Compasses a call to let them know to expect us sometime between 1 and 2pm.
Weather forecast looks good. Possibility of some showers but only light winds.
