We have never stayed in that area, but
HERE is a link to Punta Gorda on RV Park Reviews. There are 3 parks that have been reviewed, including Sun 'n' Shade.
Sun 'n' Shade gets mixed reviews. One person gave it 7 out of 10 and said it was clean (but with a lot of older units belonging to permanent residents) and another gave it 1 out of 10 and said it was dirty. Go figure.
Maybe one of the other RV parks in the review will suit your needs, or maybe someone will come up with another suggestion.
