I'm suprised at everyone saying how the OP was used and what a bad friend the other person is.
Maybe I'm just lucky, but I have a small group of very close friends, and we absolutely bend over backwards to help each other - even if it's sometimes inconvenient for us. I imagine the mom really hoped that the little girl had matured and that the sleepover would be fine (or that the little girl was comfortable enough with the OP that she would be fine - usually "sleepover anxiety" is pretty location and people dependant.)
Did it work out as you all hoped it would? Nope. Was everyone just fine in the end? Yup. Do friends do things that are sometimes a pain in the tush for other friends? When they are good friends, yes.
I can't imagine any goal of making a big deal out of this other than to make the parents feel bad and guilty. What good is that? They are your friends! I would hope you'd be happy that they got a great anniversary celebration. Consider the 3am car ride your anniversary gift to them.
OP, I would also reconsider your stance of not ever leaving your own kids overnight. In addition to the fact that getting away as a couple occasionally is healthy, and a critical componant of a happy marriage, there is a very high chance that at some point you will HAVE to leave the kids alone - an emergency with another kid, a death of a close relative, etc. You'd hate for the first time you leave the kids alone to be in the midst of an emergency. Much better that they are used to spending some time with grandma/aunt/friend so that they are at least comfortable with the situation when the time comes that you have to leave them.
