One of the many Airbnb lessons I learned on this trip: Splurge for just a little extra space, and everyone will be so much happier (or at least less cranky). Driving from Waco through Dallas to Hot Springs, Ark., we made a last-minute booking at a home in tiny Washington, Ark. Having couches and comfy chairs was heavenly after all that driving together.

But using Airbnb, especially when traveling with a family, requires carefully reading the host’s descriptions as well as guests’ comments. Extra fees for more than two guests can be a budget-breaker for families. Guest comments about partying all night with the host and his buddies indicate it might not be the ideal family stop.

Unfortunately, not every description is accurate. The Cabbagetown listing provided fair warning, saying the 600-square-foot apartment was ideal for two people. It had sleeping accommodations for four with a pullout sofa, but the owner cautioned, “Please understand that if you choose this option, it is a BUDGET option.”

I'm wondering if Airbnb has any advantage over other vacation rental websites.

Seems like it's a lot more buyer beware.
