Hi @Lovely_Lyn06 and welcome to the forum. 
It’s good that you’re “worried” but instead of passive worry, turn it into active steps to be prepared for the vacation. What NA drinks can you enjoy instead of alcohol? How to handle cravings with keeping busy and other distractions? Focus on the wonderful vacation itself - alcohol is NOT a vacation, it is a depressant and only dulls the experience. Live in each moment of it. And have fun!
