Needing a night time stop on way to Florida

We've left from the Eastern Shore of Virginia around Jan. 5 for the past 5-6 years with our Cedar Creek winterized. We usually stop around Fayetteville, NC around 3:30 (about 6-7 hrs. after leaving home)and de-winterize there. Never had a problem with very cold temperatures in that area. You will have heat on in the RV overnight, warming it up. If 32 degrees or below was expected for the night, we'd drain the water hose to the RV so the water lying in it along the ground wouldn't freeze, delaying us in the morning. Being dewinterized after that shouldn't be a problem the next day as you are driving into warmer and warmer temperatures. By the way, our destination is about 40 min. north of Ft. Myers. We spend our second night at St. Mary's, GA right next to the GA/FL border. We get to Port Charlotte early to mid-afternoon the next day. Hopefully, Fayetteville campgrounds will be OK by January. I'm sure they are scrambling to be ready for the snowbirds.
