We have squeezed in a day at Cocoa Beach and could conceivably be there from sunrise

to about 4 pm. We are driving to WDW and have a GPS, so we are good for the trip. I have the following dire questions:
Where do we get cheap kids boogie boards?
Is sunrise worth getting up SO early for?

Any recommendations for eating breakfast or lunch?
Anything to recommend specifically - place or activity?
Any particular beach/park to recommend?
What is the chair/umbrella situation?
Thanks!!!
We had thought about Kennedy Space Flight Center, but after mulling it over decided it was too cerebral for this trip!
