Honestly I kind of despair for this ever reaching an amicable solution.

Is the problem that you can book a hotel (or bnb) within the occupied territories?
Or is it you can book a hotel at something which is an "illegal" (as set by the UN but not by Israel I assume) settlement?
Does the UN want the booking services to check the ownership of the hotel to see if it is Jewish or Palestinian? Or just not have any hotel bookings there at all?
They are considered illegal by US, Canada, UK, EU, and most other nations. China generally supports the notion that this is occupied territory and generally votes in this direction the UN.
So this is not one of those 'North Korea, Syria and Somalia have taken control of some UN working group' type of scenario, nor is there really any lack of international solidarity, at least academically on the issue.
Obviously it's complicated, but there's pretty much a consensus on the de-facto illegality of the settlements.
I'm a bit confused about TripAdvisor but I bet there's just some portion of their business I'm not familiar with. It seems like reviews etc of businesses and lodgings inside settlements wouldn't be enough to reach that category.
I looked around the links on that page but I'm not getting a good feel for what happened.
Like any hotel booking site that can book a hotel room that is located in the settlement?
