I am here right now. Yes,the easiest way to get to the beach,especially for someone with a bad ankle is to take a short walk to town.
Some of the sites tend to be small, but there is often a green belt between your site and the site behind you. Often groups will be on both sides of the greenbelt.
There are lots of dogs here right now,and yes, very well behaved. Better than many of their owners. It can be noisy at times on weekend evenings, but if you call security, they should come and talk to them. I think more people should do that. 805-431-2790 :-)
