You can take a look at our Insiders here: https://www.vayable.com/users/search?query=&sort_by=popularity

I think that you are asking the wrong question. Any positive feedback you get on here shouldn't be used to make decisions about the idea unless it comes with money. The only feedback you should accept is that people say they see a need, which should prompt you to ask people to pay you to solve it.
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.
I think it would be very good and based on what I've seen, in great demand by a lot of people. I know of a site already trying to build this model called ThinkPlaces. It all depends on the quality of the experts you have. Many "travel" experts are not really experts at all, just long-term travelers with opinions.
