I'll ask the question... - did you guys break down and have sex at one point because it was your "last vacation" together and who knows what was going to happen.
Been there, done that, mind you in my situation we kept having sex for several months after that, I'll admit it, the sex is good, even after kicking her out and her having to move in with her parents, she still came back for the sex regularly, we would still be doing "it" if I hadn't put a stop to it at the end of oct/beginning of november (I forget specific dates)
Nope. Nothing beyond a couple of kisses.
As per my request, my son and I stayed in one room while WAW and my daughter stayed in another. That pretty much removed any risk.
