I've used Boingo in the UK (and Brazil, and Argentina, and the US) and can only say good things about them. It seems they have agreements with all major players (like BT, Orange, etc.) so you can use your Boingo account pretty much anywhere in the UK where you see the "WiFi zone". There are sooo many interesting places in London. Some of the not so obvious: - The National Archive - The Victoria and Albert museum - The Sherlock Holmes museum - Abbey Road (if you are into The Beatles) - Greenwich - The Naval museum (in Greenwich) - Newton's (and many others') tomb at the Westminster Abbey - Millions of others I can't recall at the moment Learn to use the Tube, it will take you everywhere you want to go but Greenwich. Also, you can spend a day or two in Cambridge, only 50' away by train from King's Cross, you can pretty much walk everywhere from the station and so many things to see. The Scott Arctic Expedition museum, The Cronophage (although it's *very* disappointing), the colleges and you might even get a glimpse of Stephen Hawking if you are lucky enough (tip: he goes for a tea at the local John Lewis every now and then. That's where I saw him :)) And by Jove, drink some propper beer while you can! Cheers

Well, never had a problem at Heathrow, and I've used terminal 4 and 5 several times over the last few years. Yup, I suppose there were hiccups with the baggage handling when Term 5 opened, but that has been solved. The coffee shops on the departure area suck though.
