Cell service is not available. We do maintain a Verizon hub that works in the office and clubhouse area, but expect to not have cell service at the park.
Wifi is free and available throughout much of the resort. The clubhouse has very good reception and is a comfortable place to use (and charge) your mobile devices. When we are at high capacity the system can be slow.
There is no cable TV at the sites, and the beautiful trees block satellite signal at most sites. We do, however, have hundreds of DVDs (and even a few VHS tapes) that are free to borrow.
