Airport transfers - London and Paris
 

Family of 4 with all their luggage and carry ons needs the best way (and cost) to get from London to down town and Paris to downtown.

If you are flying into Heathrow I suggest a car service called www.justairports.com. They will meet you at the airport and drop you off directly at the hotel. It's a lot easier than the train and probably less expensive than 4 train tickets plus taxi fare to the hotel. The tube is the cheapest option but I'm not sure I would do that under your circumstances.

You didn't like all the answers you got on your other thread?

I agree, prebooked private car service from LHR. I've used justairports.

From CDG, just take a cab. I haven't found shuttle/private car service to be a good value.

I was hoping to get an idea of costs for a number of options but no one is giving me that. With all the travel that Fodorites do I was sure some would have cost numbers for me.

Ok I'm seeing cost estimates on the other thread so please disregard my post above!
