I'm hoping to come (Midlands contingent). I won't be staying overnight, as I already have weekend plans with my parents conveniently close in Suffolk anyway.
It'll be weird being in Wymondham, I haven't been to the town since I lived there while working at Lotus, I left in 1997. In those days you could park for free in the town centre car park, which is a short stroll from the Abbey (and indeed most of the town!), I imagine there's a charge these days but I've no idea, there's maybe room for 50-60 cars (total) from memory. There was also an enterprising group of teenagers who would hand-wash you car for you, for however much you thought it was worth (long before this concept became ubiquitous using Polish cheap labour).
There also appears to be a pretty small car park next to the station, which is also a very short walk from the Abbey. There are more car parks in Back Lane and by the library, which aren't much further. The streets are mostly pretty narrow so there's not much street parking in the town centre. For this reason most town centre residents (myself included) used the public car parks for parking their own cars, but still I'd imagine on a Friday afternoon there should be space available.
