i don't personally have experience, but I understand that it requires rigorous screening both psychologically as well as physically, and an understanding that you are carrying someone else's child, and they now have a "right" to tell you what to do, to some extent. It's a decision that not only involves you, but your whole family. For instance, if your spouse smokes, and the parents don't want their baby exposed, they could theoretically insist that your spouse quit (of course, they may not select you on that criteria, too).
I once watched a documentary about a surrogate pregnancy, and I recall the conflicts the surrogate had with the parents, as the parents did not want her to engage in any activities that jeapardized the pregnancy, including flying. Also, how will you feel about giving up the baby, possibly to a couple you don't approve of? You later learn something about them that makes you question their ability?
