We'll be coming from Kapaa to try snorkeling at Kee Beach in a few weeks (our first trip to Hawaii) and I'm wondering if we don't get there early enough (before 8?) what our options are if the parking lot is full. Is there another lot further away? Will the places that you can't park be well-marked? The last thing I want is a ticket. How far of a walk would it be if we parked at Haena Beach Park and walked to Kee and then back to Tunnels to snorkel later in the morning?
