Can someone describe what it's like to go to Shell Island. How do you get there? (boat from Panama City I believe?). How much does it cost? Do you bring your own food? And is the shelling/snorkling really that great? How long do you think is a good amount of time to spend there? (a few hours? all afternoon? all day?). What kind of shells do you find (e..g, olive shells, bonnet shells, etc.). We've been thinking about trying that out (but then we get so lazy when we're there that we spend most of our timing at the beach, pool, porch and doing the things we already love to do. But I've been thinking about shell island for a while. Thanks.
