As far as vacation goes, I'd say to eat at maintenance calories for your vacation but to try to make better choices (fruit instead of cake, for example, or light beer instead of regular) in terms of your diet.
Once you get back, look closely at your process. Are you logging all of your food? Are you planning ahead or just trying to wing it (which leads to the binge problem)? Have you been restricting too long because you wanted to put off your break? That could have set you up for the binge behavior right there.
If it's a matter of needing to track your food better but not wanting to put forth the effort for doing that, why not try
Leigh's One Big Meal idea? You make one big meal that should last you the whole day. You can do this by making a big pot o' whatever (soup, stew, chili...there were a bunch of different things suggested) or by planning ahead and putting your "One Big Meal" onto one big tray in your fridge. For the course of the day, you are only allowed to eat what's in that meal (or on the tray). You figure out the calories and macros ahead of time, so that when you're following this plan, all you have to do is to remember to eat your one big meal and nothing else. It's a pretty easy way of tracking your food intake without having to think too much during the day.
