At 16, you should completely forget about things like "bulking" and "cutting," and instead concentrate on eating whole, mostly home-cooked food with lots of lean meats and vegetables.
"Bulking" is a fancy way of justifying eating like an idiot, & "cutting" is a fancy way of saying eating like a bird. Yes, both may come into play in your lifting journey down the line when you get into weight-class sports or whatever, but that should not be your focus right now.
As for the lifting, just pick-up where you left off. This is also why having a correct training max is important (80-85%), because you can come back & pick-up right where you stopped.
Best of luck, and enjoy every vacation you can. And remember, lifting should enhance your life, not detract from it.
