The last & next three days have & will be spent seeing a few of the many sights that London has to offer (with the help of my trusty London Pass saving me many, many pounds - londonpass.com). I'm not sure when the holiday part starts - after the busy weekend in Basel, it hasn't really let up with many hours spent walking, reading placards, sitting/standing on the tube - still it beats shift work.
With walking around London being stangely familiar & a case of happening on landmarks, it's been quite enjoyable. Highlights from the last three days have been Windsor, especially St George's Chapel & the State apartments with all the portraits; Eton (seeing students' names carved in the stone from five hundred years ago is a little strange when your own country isn't anywhere near that old); Tower Bridge & the old steam mechanisms that raised the deck; and HMS Belfast - one of the only surviving big gun ships from WWII.
Hampton Court Palace, Kew Gardens, St Paul's, Greenwich, Imperial War & many other museums to sneak a look at.
