Significant birthday for DH. We have 24 hours in Central London. Thinking of going for lunch then doing an activity/attraction in the afternoon that we wouldn't/couldn't do with the kids before going for drinks/dinner. Prefer something not too booze fuelled as will spoil the evening. Thinking along the lines of Up at the 02, except I hate heights! A boat trip? I'm stumped! Probably worth mentioning that it will be between Xmas & New Year.
