We stayed for a week at Mission Bay RV a couple of years ago when we were adopting our rescue pups. It was a bit expensive, but not terribly so, especially considering it was so clean, well kept, close to everything we were interested in seeing, pet friendly, loved walking down to the bay, and taking the pups on their daily constitutionals just outside the park on the Bay walk, the gate is locked and the walk is sided by the bay on one side, and a residential trailer neighborhood on the other. Besides the locked entry to the walk, there was round the clock security in case of any problems, which was nice, although the park was so quiet, it didn't seem necessary, but we appreciated it anyway. We really enjoyed our stay there. They have their own beach...check out their site on the internet...they have a virtual tour, and the pictures are accurate... so you can see if it appeals to you.
