The service would allow you to search for travel experts by destination or interests and schedule calls with experts to help plan your trip. How much do you think one will be willing to pay for this service?
I agree with Willis. I think it's a really dangerous and misguided idea to try and validate any idea (especially something like this) on Clarity.
Simply put, you're going about your customer development process completely wrong. Happy to try and help you get on the right path in a quick call. A lot of my other answers here on Clarity have spoken to early-stage ideation and finding product-market fit as well, so hopefully you find some answers there.
