My wife is on vacation

So since moving to Minnesota 3 years ago I have been to France twice and back to Virginia once for a total of 13 days gone. My wife has been gone 1 weekend, grand total 3 days. If my math is correct, I am ahead by 10 days. With that said she is on a vacation by herself. Here is how it went down:

Wife: I would love to go to Arches and take pictures (National Park in Utah)
Me: Ok, go.
Wife: Really?
Me: Yep.
Wife: No really?
Me: Yep.

And she was gone 2 days later. She deserves it, but that is not what I plan to talk about. Most of you know I have 3 daughters, who are really wonderful, smart, sweet little girls. They try my patience from time to time (truthfully I am a passable father at best), but none the less I could not ask for better kids. So my dilemma was this. What do I do for 7 days to entertain them? Luckily they have school 5 days out of 7 so I will have time to clean and cook. But what activities do I have for them. So far today we have made sock puppets and cookies. Later there will be a puppet show and hopefully laughter. Tomorrow I plan on going to the zoo or another venue, just to get them out of the house. Yes I am a brave man. Then the next day is school, and I can recover a little, or plan out the hunting trips I have been promised. :)

So far it has not been to hard, but I do anticipate some breakdowns on both their and my part. I told my wife to check in every so often so I know she is okay and she knows the kids have not caused me to run and hide in my closet rocking and sucking my thumb while in the fetal position.
