Vacationing

My boyfriend and I are both 16, about to be juniors in high school. We’ve been together for a year and 6 months. My sister lives in Florida while we both live in Michigan. Would it be wrong for us to go on vacation together down to Florida and stay with my sister? We aren’t really looking to have sex anyways, just want to spend time together. Even if we did have sex, I’m on birth control and I have condoms. What are your opinions?
