I would order from Jeannie, 2 cases and whatever else.
Your prep time could be spent on dinner and / or excursion reservations, fresh flowers for wife's arrival and checking out some stores on the way to fave beaches - ie there is a small grocery in Hope Estate, just in front of what looks to be a new BMW dealership. Bacchus in Hope Estate has some nice foods and maybe some wine shopping
All that sounds more fun than chasing down and carrying home 2 heavy cases of beer!
Regardless have fun
