Our first vacation together was a disaster?

Me and my boyfriend been dating for one year and just came back from our very first vacation together. We used to spend weekends together once in a while but not more than that. A couple of weeks ago we went on our first vacation together for 15 days and it was a complete disaster. We never argued like this before but during our vacation that was supposed to be perfect we ended up having so many disagreements almost every day but never stopped loving each other however, I didn't feel like that was the best environment. Anyone ever experienced something similar? What can we do to avoid this the next time we decide to go on a vacation together? I was actually disappointed because we never used to argue or fight before and really don't want this to become a habit in our relationship. Sincerely looking for useful tips from experienced couples
