Watched 5 or so racoons around a group at a campfire in Ft. Pickens. One would reach into the KFC bucket and pull out chicken- right under the picnic table where people were sitting. The people never saw them doing this.
St. Marks is a little out of the way, but cool little village with motel. Not much in the way of food along 98 in this area.
I've not had good luck in SPs in the Everglades during spring break. Maybe north FLA is better though. Will be riding a week long trip first week in March up that way, but a loop.
I like Wakulla Springs Lodge if you are taking that route as opposed to US98.
