Here's an inexpensive and adventurous option for all you outdoorsy gals. It's as simple as throwing a sleeping bag, tent and cooler of food in your car and taking off.
Designated campgrounds often come equipped with drinking water, bathroom facilities or showers. If you don't care about these conveniences, you can get more privacy and adventure by backpacking in to a remote site in the back country. It's just you, your girls and nature. Hike, mountaineer, river raft or do whatever outdoor sport suits your fancy. Gather around a bonfire, roast marshmallows and share stories (after all, that is one pastime we're good at!).
