Without the prompts or knowing how specific they are I think it's rather disastrous how similar they all are. But that's probably why many can catch an AI generated/designed page in an heartbeat. If the prompts weren't very specific and you get similar results from different models... then I think we are looking at a rather bleak and boring web.
These popup weekly now. Like all the other "AI travel" things it's useless. I used to work in the travel space and still have interest in it so I've seen them all, the vibe coded to the hundred million dollar incumbent solutions like the soon to be released Expedia updates. They all suck, lacking domain knowledge and understanding of what travelers want, need and enjoy.
