Is there cell, internet service there?

Yes but very limited. There is only one spot near the restaurant and the pool. Outside of that the whole area of the campsite has no connection.

Cell depends on where you are and what service you have. We have Verizon and were able to get two bars some times as the campsite but others not. To make calls, I ended up driving back to the road. Even there, cell service went in and out unless we stopped at a good spot.

There's WiFi access only in the adults lounge.
