Look at my dongles!

[Mule]

A friend and I have both recently decided to go travelling in my VW campervan around the country. I've fitted a mains power source to it so we can use our laptops but we're going to need internet. I'm thinking dongles unless theres a better solution, or even one dongle and linking the pc's. This journey has a starting point and that's it, no itinerary, so we could be gone for weeks but a contract longer than a month shouldn't be necessary.

So yeah, internet solutions please?

Any other ideas also accepted, we have a 22" TV, fan heater, will have a CD player and have arranged to meet several ladies on our journey
