first recommendation is to slooooow the shutter speed. The beginning shots with the bridge was near unwatchable due to how fast those pillars go by but with zero motion blur
for the rest of the video my advice boils down to you don't have enough variety of shots and could therefore cut about 80% of that, all the beach shots look the same, all the Disney shots look the same, and the fireworks could've been 3 seconds instead of 30+. Edit shots that are visually different and progress the story because if they are all super similar and the viewer can scrub through and basically keep scrubbing through the same looking shot, they'll just scrub to the end and not watch
for a fam trip like that I know its easier said than done to get the exact shots (and big variety) you want since the focus is family, but next video keep variety and shutter speed in mind!
