Bringing stuff onto the beach

Headed to CP tomorrow, planning on spending the first day at the beach and pool area. Is there any limitation on what we can bring onto the beach? I’m think along the lines of water, pop, snacks, beach chairs, etc. Also are umbrellas or anything available for rental?

Thanks!

There is beach furniture but it is free. I don’t Think they have any furniture for rent but i wouldn’t know as I always used the furniture that was already on the beach
