We can't fully rate this park as we stayed there only one night and didn't do much exploring.
Upon check-in you have to park at the gate, exit your vehicle and enter the Welcome Center. Entrance to building is at street level. Initial impression: minus a star for having to get out of your vehicle.
What we can tell you is that the park is quite hilly. Initial impression: lost another star.
WiFi is available only at the lodges and it's not very good. The entire park is a dead zone for cell phones. No signal with AT&T, Sprint or Verizon.
There is an indoor pool.
Although the park is absolutely beautiful and you can hear the ocean, we will probably not return due to the hills and the cell signal dead zone. Reguar people will LOVE this park (except if cell service is an absolute necessity). Special needs folks are presented with a challenge.
