Headed south for just two weeks

We are relatively new to RV'ing, although hubby is an almost retired truck driver. Bought a used truck and older 5th wheel, 28 ft., last fall and decided to try out the RV life. Have taken a couple of quick overnight trips to get used to it, that's all the time we've had. Headed for Florida, god willing, on 2-23-19 for a 2 week test trip. We've made reservations at one park, Hickory Point, near Tarpon Springs, for 2 days, but are wondering about parks further south, availability, prices, traffic, all of that. We haven't been to Florida in 15 years. Hoping for lots of advice from folks that are in parks down there...thank you!
