Movie where there is invisible monster they kill with paint cannon

When I was a kid I rented a movie where a group of teens went on vacation. They then encounered an invisible alien that they identified the location of and killed him by shooting him with a paint cannon. That is all k remember that and some really bad CGI. Any help would be much appreciated.

  1. I remember a movie like this too, didn’t the alien have a sword or something and cut a girl in half? And would have shots of just the feet movie through the sand or something? I was so little when I saw this
