haha, we have a long layover in London too.
That's what I said...we're gonna go run out and grab some fish & chips to say we ate in London. (we have about 4 hours) So this is a good question for me too!
FYI -
If you arrive at Heathrow Airport you will need to take the Heathrow express into London which will be about 40 min (if you catch it on time) and even when you arrive at Paddington station, there really isnt any place near there that would be fun to see, so you will have to than take the Tube to Covent Garden, Tralfager Square or even Piccadily Circus.
If you arrive at Gathwick Airport (sp.?) It will take a little longer to get into London... and the above applies also when you take the Gathwick Express to London, which brings you to Victoria station.
Make sure you plan accordingly!!
do you know where prince harry hangs out? cuz that is what i'm concerned most with. that and a good cup of tea.
He is probably at Windsor Castle... but thats a whole other day trip in itself...
