i would agree with roberta and go with the entrance. I would also suggest that you stay right

here it is where we had the raiders stay its right on the water and its a short walk to the beach for salmon/jewis or you can fish the entrance channel for some monster flatties ive seen caught there. Its a very nice park too, not sure bout internall heating.
Cheers,
