Yes gpt 4. I was fact checking and using places I knew pretty well and would find the occasional error when asking it to describe cities etc and what to do.

Well for itineraries, given that its training data gets cut off at some point, I’d also be worried about it recommending places that are no longer open.

Note that I’m building an app for customers and attempting to build a brand that can be trusted - whereas in your case gpt 4 is probably ideal given you know it’s caveats and can check the important stuff.
