Vacation?

We just took our girls out of town for a few days for a last minute spring break trip. Everyone had a great time. Weird thing about vacationing with children, they really seem to have a much better vacation than we adults. Why is that? Could it be the packing, unpacking, working out all the little details to make sure everyone's needs are met, etc? Hmm. I really did have a good time but I can't seem to help feeling like since I got back I need a big nap.
