Have you tried Purple Parking?

I just did ... and it's DOUBLE what it would cost me to park at Cardiff. Yikes! At least then I wouldn't have to pay for a flight from Cardiff to Paris ... but (man, this is so confusing!) ... the London flights are pricier, anyway, so I'm not sure if it makes a difference. Thanks for the suggestion, though.
is there anyone in London you can stay with to get there early?
I've stayed with my aunt & uncle in Elstree before -- it's about a £20-25 taxi ride to Heathrow from their house. But their house is SO FILTHY that I'm not sure I can stomach staying there! I know it sounds like a flimsy excuse, but seriously, if you could see their place you'd understand. Plus, I'm not very close to them and am already feeling guilty that I've moved to the UK and have only seen them twice in 2+ years. If I stayed over, I'd feel like I was just using them for the crash pad ... which would pretty much be true.
But it is always a back-up plan.
belinda, what night is this? you can crash with us-on our blow up mattress. Caryn's done it! (bahlmeron). WE're a 6 min cab from paddington (heathrow express) so really, you're there in under 1/2 an hour.
Thanks, Amy! I'll keep it in mind. You guys are all so nice!!!
I can see this is going to take a few hours of steady research when my mind is in focus-mode -- which it most definitely is not at present!
