MCO shops - beer/wine/liquor/soda?

Is there somewhere in the airport to pick up beer/wine/liquor/soda? If we take transport directly from MCO to port, we wont be able to make a stop....

Short answer: no. You can pick up sodas and bottled water at the newsstands and snack bars, but at premium prices.

There is a Duty Free shop at the Hyatt inside the airport. Not sure if they carry wine though.

Are you traveling directly to the port via cruise transfer shuttle or private shuttle?

Sometimes, depending on number of other passengers, a private shuttle might be able to stop at the Walmart off Beachline and Rte 1 before crossing the causeway. But you should arrange with the shuttle service before hand.
