Vacation Support!

I've recently started a pretty structured meal plan revolving around 3 meals and 3 snacks a day and have had pretty good success so far. However, I'm getting ready to go to the beach. In year's past, beach week could also be named food week for me and my family. Love everything about seafood and everything else that comes with vacation eating! Does anyone have any tips on how to keep on keepin on with healthy eating and staying away from nonsense food?
