Agreed the day off work and just booked my train tickets. Arriving New Street 11:45 and returning on the 20:10 Virgin train - probably the same train as RogerB so I’m hoping he’ll wake me up at Watford. £17 for the train and I’ve added the PLUSBUS option at £2.20 in case we decide to explore further afield.
Don’t really know much outside of the Briar Rose, Wellington, Joint Stock and Prince of Wales so will rely on others, there seem to be enough recommendations for a good day.
