The biggest issue is resuming your healthy eating plan when you get home. And yes the scale will go up due to water retention from travel and eating so much sodium , but drinking a lot of water helps.
But for me I weigh (no pun intended!) the value of each treat to myself. The churro or sickly sweet pina colada from the pool bar doesn't tempt me at all, but splitting a hot fudge sundae does the trick. I don't waste calories on soda, but will have wine with dinner. I skip the bread basket and don't waste calories on breakfast pastries, but will have the eggs benedict or other savory options. I almost always split desserts instead of eating the whole thing.
