What is the difference between them? Anyone used both and can say which one they like better? DH and I have used AirBnB (in Europe) and absolutely loved it - we've sworn we'll never stay in another hotel as it is that awesome, especially if we want to bring the kids along. I keep hearing about VRBO though (mainly from North American friends) and just took a look at their website - it seems to be similar to AirBnB but maybe not as user friendly? Is it more American based or do they have a lot internationally as well?

If you've used both or either one, pros? Cons? Would you use them again? Which is your preference?
