St Albans is about 40 minutes from Aylesbury, and well worth a visit for some culture and retail therapy. Our provisional itinerary is to arrive in St Albans at 10:45am for a visit to the Museum of St Albans. We'll then go next door to the Courtyard Cafe for some lunch (delicious and not too expensive) before heading into town to browse the market. At 2pm we'll join a free hour-long tour of St Albans Cathedral*, before strolling back through town past the shops. The plan is to leave St Albans at ca 5pm.
* If we're more than say 6 people we may have to get our own tour; I'll need to confirm the price.
