When I went on Sunday they only briefly checked bags at the door so yes you can bring in your lunch. There's plenty of eating areas with tables downstairs in the dolphin viewing area and on Sunday there were families having lunch there with outside food.
You may not br able to bring in backpacks, but you may bring in food.
You can't, but you can leave your backpak with lunch in a loker so at the moment you are hungry you go out to eat and you can re-enty
I do not think you can. You can eat out side but they don't even like backpacks in there.
If i remember correctly you can but, I'm not entirely sure they might have changed their rules and policies.
