Should I cancel our “baecation”

Hi guys so me and a guy I’ve been seeing (not exclusively) planned a trip to Mexico in March. Well I saw some things on his Snapchat that I didn’t like (he went on a boys trip to Vegas) and he went to a strip club and I don’t like it. It’s a new year and I want to date a serious man not a man child. So I want to cancel the whole trip because I don’t want to waste my time with him anymore but I wanted to go because I never been...what do you guys think cancel the trip? Or still go & dump him after the trip...or let him know before we go on the trip that I’m looking for something serious and if we go it’s just as FRIENDS.
