here's how we go from Oklahoma to Florida:
I-35 south. We like Twin Fountains RV Park in Oklahoma City.
I-35 south to Denton TX. We stay at McClains Wagon Master RV Park in Sanger TX. Not fancy but good for overnight stop. If you want to see Fort Worth, we like either Cowtown RV park or Oak Creek RV Park in Weatherford TX. It's a better park but more of a drive into Fort Worth. Also there is a corps of engineers park at Benbrook Lake that is closer to the Stock Yards.
US380 east to Greenville TX.
US69 south to I-20.
I-20 east to Shreveport LA - we stay at Fernbrook RV Park in Longview TX.
I-49 south to Lafayette LA
I-10 east to I-12
I-12 east back to I-10 east - we stay at Lakeside RV Park in Livingston LA.
continue on I-10 east. Our next stop is the KOA in Milton FL.
Just east of Tallahassee, take exit 225 (US 19S)
In Perry FL take US129-27 to US 41 south
US 41 south to Williston FL (stay at Williston Crossings RV Park)
Continue on US41 south to Dunnellon FL and stay at Rainbow Springs State Park. (make reservations) This is a short drive from Williston so you can move RV sites or stay at either one.
Continue on US41 south to Inverness FL
take FL 44 east to I-75.
I-75 south to either Tampa then I-4 to Orlando or take US50 east to Orlando.
If you go toward Tampa, we like Quail Run RV Park in Wesley Chapel.
If you aren't going to stay at Disney Fort Wilderness, we like Tropical Palms RV Park in Kissimmee. They have a shuttle $$ to Disney.
Have a safe trip!!
