What a wonderful vacation! Our first trip with the camper literally "on" the beach.
I have been dreaming of doing this kind of trip for a long time but I will say, it is definitely something you need to be properly set up for. I watched a number of poor souls during our week's stay get stuck, not only in the sand, but at the shore's edge. I watched a full size pickup almost get swallowed into the ocean. Little errors here can lead to major losses but proper preparation almost guarantees a great time!
Loved every minute and we plan to make this an annual family trip.
