At the suggestion of a poster on the London form (AdamsHornets or some similar username), my mother, another friend, and I are planning to spend the morning/early afternoon on Sunday, 16 December in St Albans prior to visiting the Harry Potter studio tour. We'll arrive by train from London to St Albans about 10 and leave from St Albans Abbey around 15:30. I've heard that there is less going on in St Albans on Sundays, but that was the only day we could book the studio tour. We would like to see the Roman ruins (these are at Verulamium Park, if my research is sound), have lunch at Ye Olde Fighting Cocks (or another pub if anyone has a better suggestions--I like that this one claims to be so old), and perhaps tour the Cathedral, but I know that tours don't start until 1430 on Sundays, so I'm not sure we will fit it in.
We're not tied too closely to this itinerary, except for the times, so I would love to hear other suggestions. We picked St Albans because I understand that while it is a London suburb it retains a bit of a village quality. My friend lives in London, but my mom and I are only there for a week, and I want her to get to see a bit of England that is different than London (so we're going to St Albans and Windsor). Given that, maybe it would be better to skip the park and walk around the High Street, I'm not really sure and would be very grateful for advice. Thank you in advance.
