Trying to plan a trip

Our family has decided to plan a quick trip at the end of Ohio.  We had decided when we canceled our beach vacation that we would do something to support the Ohio economy.  It is proving to be harder than I had anticipated.  We have a three-day window at the end of July that we can make a trip.  It's even during the week which I thought would be easier, but it's proving to be challenging.  I am hesitant to do things that require being indoors because I wonder if they will be open.  I am hesitant to schedule too many things outdoors because that is tough on my health.  I don't want to be too far away, but too close doesn't work either according to the rest of my family.  I want to relax and not have a schedule, but I don't want to just be sitting around a room doing nothing.  We can do that at home for free!  I am beginning to feel defeated!
