I’m cruising on Carnival. Is there somewhere near the port where we can buy some six packs of soda and beer to take with us.

Cant bring beer and only cans of soda are allowed (at least on Carnival). 12pk soda per person.

A couple of blocks away near a waterfall they have a liquor store were you can purchase soda make sure it's in plastic bottles .

No plastic bottles, only cans of soda - if you are of age, you can take 1 750ml bottle of wine. Don't forget an opener!

There is a gas station I think it is a k best I remember it is about 3 or 4 blocks away. But what we do is get soda near the hotel we stay at

Definitely no beer. They will run your bags thru xray machines

I will tell you know they will not allow you to take beer on there but soda you can I just got back from the Cruse in February unless you find a way to sneak it on the ship you can't but there is a dollar general about 2 block away from port and make sure that you got cash because they don't take bank card when you go to pay for parking any other ? Just ask me my cell number is 8282014294 just let me know your asking about Cruse stuff when you message me

There is a gas station on the way to the port, where you can buy beer, soda, etc.

Not right at the port, but a number of shops within the surrounding blocks.
