Just saw this ... we used Prestige cars and loved them so much we plan to use them just to get to and from the airport anytime we fly; I'm sure they or someone like them could do it. We brought the maximum luggage allowance, and they sent this big suv. We filled the back with luggage and sat in the back seats. There would've been room for a couple more people and some more luggage. In your case, due to the dogs, you may want two of these vans. It was 45 pounds from Heathrow to Wokingham (near Reading, which is where we stayed while we looked for a place to live). It would be quite expensive with two cars, but ya gotta do what ya gotta do! If you can't use Prestige where you're going, ask your relocation agent and she can probably hook you up, maybe even get you a deal!
