What should I do with my mom?

HelloSweetie4

My mom is on vacation from work this week so she asked if she could tag-along on my and my husbands day off this wednesday. I just don't know what to do with her... The weather is going to be around 70 but with periods of rain. She's not a very active person so she wouldn't be up for a hike (like what we usually do on our day off). I don't want to plan something outside and it ends up raining all day either.
Any suggestions?

Not sure where you are located but how about a museum? That way you get some walking in and it will be indoors in case it rains.
