My home is right by a community beach access and I sit on my porch early in the mornings (7-9) and watch locals and tourists pull their vehicle (car, truck, van, golfcart) up to the access and unload their chairs, coolers, umbrellas, tents, toys, surfboards, etc. and then get back in and go home. They go back to bed and come back around lunch to spend a few hours. Then they go home for naps or out to eat a late lunch and leave it there for hours, only to come back to sit in them to watch the sunset, load up, and go home. And that is fine. There is really not difference between them doing it and the vendors setting up long before their guests (who paid them to set up) come to sit. If you are going to say vendors cant do it, are you going to go after the people in their store-bought chairs too? The beaches are crowded, and you can no longer expect to lumber down there at 11 a.m. and get the best seat. It doesnt work that way anywhere.
