Should students have homework during school vacations?

My school had off last week, and I spent the entire time in Florida – left at 3 am saturday morning, and back the next sunday night . I had a math project, an essay, etc as assignments from my teachers. I tried to get it done as quickly as possible, but the workload still severely affected the trip. I realize that teachers have a limited amount of time to get things taught, but my parents argue that a vacation is called a vacation because you are supposed to relax. Opinions?
