Why do record offices, libraries etc pick Friday for their closures? If you live out of London, Friday night is one of the cheapest for hotels. So it makes sense to come up on a Friday, visit a record office, stay over night, visit the record office on Saturday (if it's open) and then buzz off home. Sunday night is also cheaper in London hotels but the record offices are open that day so you'd only have Monday to do your research. Midweek is usually the most expensive in London hotels. I know everyone won't agree but I just needed to get that off my chest! Mark @ Yetminster (which isn't in London)
