If you want to save money and do something close my parents took us to Sister Bay in Wisconsin. It's a part of Door County and you can visit small and fun things for your kids. When I was a kid we stayed at Little Sister Resort and our family loved it because other family's with kids also came up every year. They cook awesome home meals for breakfast and dinner. So your on your own for lunch. They have a fish fry on friday nights. Our family loves it up there so much my mom bought a vacation house and we go up on the weekends. Sometimes I miss just the surroundings of little sister resort and the people that work there so we go and eat at the restaurant they have on the water called fred and fuzzy's. Just to catch up:)
I have a 16 year old step son and a 2 1/2 year old daughter with one on the way. My step son loves to go biking, hiking, miniature golfing, go karting, fishing, and in the winter they have this crazy high hill to go sledding down and his buddies love it! Then with our little girl we have a couple small zoo like farms to meet and feed the animals that are run by local families. You can milk cows to feeding ponies (which most little girls love ponies!) They also have an amazing Art place called "hands on" it has so much for everyone in the family to do. My daughter likes to do clay or painting pottery as best that she can! My step son and his friends made some really cool signs for there bedrooms in the metal barn. You can do painting and glass making etc. I could go on and on!! If you need any info please let me know:)
