Most Florida beaches do not allow dogs.
Anywhere in Florida on the beach in December where it is warm is probably reserved already.
South Carolina state parks run a snowbird special: 50% off a monthly rate December through February: "The South Carolina State Park campgrounds at Colleton, Edisto Beach, Givhans Ferry, Hunting Island, Huntington Beach, Myrtle Beach and Sesquicentennial (in Columbia) would like to offer you a 30-day campsite reservation at half price! 50% OFF! This special is valid for reservations that encompass the period of December 1, 2014 through February 28, 2015."
We love the South Carolina State Parks on the beach. Some of the sites also have sewer hook ups.
