Thanks for your input. We opted to stay home. Okay, in reality, my wife opted for us to stay home. I would have been fine with going even though I know I would have felt mildly bad about it on the morning in question, albeit for about seventy-four seconds. Don't misunderstand me; I think we parents have a responsibility to give and give and give to our children, but just like everything else, there are limits. I also think we have a responsibility to our spouse and that relationship. In this instance, I felt like my wife and I deserved a few days away for ourselves. For me it outweighed hugging our daughter the first morning of her senior year of high school, even though she requested us to stay home for that. My wife, however, would have been miserable the entire trip, so there really was no reason to go.
It is still killing me, though; the airfare/hotel package normally would cost us $800+, but Southwest had a crazy promo for our area and we could have gotten it for less than $500. Urgh. Alas, we won't be going this year. It was the only time we could go for more than 72 hours, which is my absolute minimum even for Vegas. I will try my best to not hold this against either of the most important women in my life.
