My boyfriend is taking long to answer? Am I over reacting?

So my boyfriend went to Mexico for winter break two weeks, I know he's not going to answer right away I know he's going to be having fun and be distracted. I know he gets signal because he updates story's on snapchat or is on Facebook, anyways he literally takes like 6 hours to respond. Our conversations are so dry! They're mostly like what are you doing we do tell each other we miss each other or that we love each other but it's like ugh. I don't know if this has nothing to do with it but when I used to be in a long distance for two years, and not having him with me especially seeing him everyday I HATE remembering that same feeling all over again, like I said I know it's just vacation but I feel so impatience. Am I over reacting? I do go out with my friends so I get distracted too
