Yes on the shop. And most likely on the necklace.
Yes there is a gift shop and I believe there are shell necklaces. There are a lot of other gifts as well, including shells and starfish and toys.
There are shell necklaces and shell keychains!
Not sure about a shell necklace for sure or not. I know they had ones with "peals" in them
I remember shell coin purse type items but not sure about necklaces.
Yeah the gift shop is in the entrance. They sell shells, mermaid fins-i don't remember shell necklaces but I'm sure they have them.
