alt Hacker NewsI think some of those tasks are part of the fun of a trip - doing the research on locations, events, restaurants, etc. You stumble through a bunch of things and little nuggets of that sit in your brain and then when you're on the trip they might come up - one place is abruptly closed, something looks like a bummer in person, etc. Without doing that research yourself then on the trip you have a list of things and aren't really knowledgable about alternatives.
Like I said, I'm not the target audience for a personal assistant. That does sound like a more ideal UX than what chat gippity and the others offer though. I would expect that with Meta - they really get the UX mostly right for people.
Sure, I get that. For this particular case, I've been to Vegas (family lives there) "plenty" so I don't really care much about stumbling upon stuff like you pointed out. I just wanted to have some places on hand to suggest for dinner and things to do when the group when we'd inevitably get to the "so can someone decide what are we doing for dinner???" part of the day. For planning a long trip to say Tokyo (never been) for vacation I'd do the regular stuff searching Google and reading blogs, but I'd also add AI search to it, if anything to find the current new "viral/trendy" stuff that I absolutely do not keep up with.
