Is it worth building another vacation trip search engine what can do more then others available on web?

I was about to abandon this idea when one of my friends asked for a solution on Facebook and my idea was the only answer. The idea as to build an engine where You can set Your
– budget available
– start location
– range of dates when You can go – like September + October)
– length range (like 10 to 15 days)
– type of destination – like beach or historical treasure or mountains (exact locations is optional)
– services needed – flight, accommodation (hotel/airbnb), car/airport transfer

The result would be like 5 proposition that You can restrict (like I do not want to go to Spain or to Paris as I was there already).

So there are number of common existing solutions, like:
https://www.expedia.com/ can search flight+hotel+car but on fixed dates i and fixed destination and no airport transfers.
https://www.wander.am/ can search flight+hotel with no destination set but on fix dates and no airport transfers and cars. https://www.kayak.com (the best I think) can search flight+hotel+car (but independently) without destination set and has a range of dates and the length range. However You cannot set the destination type and no option to set a budget of entire trip as all the services (flight+hotel+car) are independent and there is no airbnb and airport transfer option.

Compare to the competitors do You think that this new trip search engine would be worth to build?

Thanks for help
