We have been there several times and it is one our favorite parks. Spent most of February there last winter. We really like the park. Great hiking and biking trails. The entrance to the park is only about 1/2 mile from the beach. We biked there several times. The sites are not close to each other. It is cooler than places further South but usually not real cold. During the winter it is full most of the time. They save some sites that can be rented for only two weeks at a time.
Somethings can't be left alone. Software being one. I suspect the old application was out dated and not going to be supported anymore.
We'll all learn to like it. No choice.
I believe the old software was the main reason for this change. Probably not being supported.
