One getaway I would highly recommend is a weekend visit to a state park! I live in Indiana, and you can reserve a cabin for $25 to $35 per night. The cabins are furnished, have electricity, private bathroom and shower, and kitchen. You bring your own linens, dishes, etc. There is no television, which I personally felt was an advantage. We brought cards and board games for entertainment, but you could bring a TV if you really needed one. We stayed for a long weekend and went hiking, explored a cave and a waterfall, went horseback riding and swimming. It was wonderful!
