Hi,
Agree the battleship park is worth a visit. Also old mobile. Free parking at the visitor center right off I 10. A replica of the old fort with a lot of interesting exhibits, from there it's a nice walk to old downtown. The Mobile Museum is just a short walk and also a worthwhile visit. We spent the winter a couple years ago at Bay Palms Campground, just before the bridge to Dauphin Island. Driving along Hwy. 90, visiting the old forts on both sides of the bay and the nature center(s) are all worthwhile day trips. Lots to see, enjoy
