No matter where you are or what you experience, you are the only constant. Dinner with friends or a vacation isn’t an invitation to forget your fitness goals because the progress made on them improve every experience you have. Different meal options don’t eliminate your desire to enjoy comfortable digestion and a flat tummy. That doesn’t mean you can never indulge in bad food, just limit it to avoid tummy troubles and bulges. A vacation isn’t a hedonistic free for all, it’s a break from some of your normal experiences. Remaining completely inactive while stuffing your face is a recipie for disaster, or at least disappointment.
You are the sum of your consistent behaviours so behave accordingly.
