The lower CG is bigger but most sites are very small and suitable for tenters, the sites on the open lower end (13-20) are best for TTs and RVs, but no shade. CG has dumpsters, water but no cell signal, whereas the upper CG does get a cell signal. Sites are now cashless and you can either reserve or pay online as you choose a site, no FCFS like previous years. Guess you need to go up to upper CG to get cell though? This lower CG is close to the marina mini Mart store.
