Can you see the park's WIFI hotspot? That's the first priority. Sometimes the WIFI network is open but some parks put a password lock on theirs. Talk to them when you check in. And you can always bring your notebook to the park office and get them to walk you thru the steps to logon. I had to do that once at a park near Great Sand Dunes, this park had a particularly arcane logon with a 20 character numeric password.
