My friend (another FTer) and I will be in London from March 3rd to March 6th. It's my first time to London and I was going to sign us up for one of the double decker tours that lets you get on and off, but the tour itself only last two hours if you take it straight through. Does anyone, either a frequent London visitor or a Londoner have any ideas about sightseeing tours/tips? We'd love to meet other FTers while we're there if anyone is in town.
