Walking tour of Guildford in Guildford

I am going on a surrey young ramblers walk on Saturday and wondered if anyone else fancied it too....it is a really easy walk, only 2 miles, see details from website: Our guide will describe the history of Guildford and take us around the historic parts of town including many of the old pubs and coaching inns. We will finish outside the Angel Hotel and then head down to the Star Inn for drinks. The tour will take about 1.5 hours and costs £3 per person. Proceeds go to charity.
