Remembering vacation

Always the first question I'm asked upon returning is "So, how was your vacation?"

Should I respond with "Oh it was great. So relaxing and nice to get-away."

Or do I say, "Honestly? It was fun and incredibly stressful. The kids can be really hard to be with for such long periods of time. But then they do or say something priceless that just blows me away."

"Oh, and it rained a lot during the end of the week."
