YES!! We spent most of the winter in FL and used Passport and our C2C membership...the most we paid was $13.50 for full hookups. There are some Passport restrictions...some parks will not honor them during certain months or restrict how long you can stay, but with a little planning it worked great for us. Our "little planning" meant calling a day or two before we planned to arrive and sometimes we did have to call more than one campground. We never just pulled in expecting a site. We saved enough on camping fees to pay for our membership for another couple years!!
Recommend you go to top and click on magnifying glass and do a query regarding Passport America for the last 6 months. Pull up a chair and coke, you will have some interesting reading. Most very favorable.
