Hi, Sorry for the late reply.
Unfortunately, CityTours theme has not such feature. It shows not only the hotel, but also some other related tours and hotels in map. So it can not redirect to google map.
When I click on the map of a hotel, I want it to get redirected to google maps in the mobile view of the website. Can you please confirm if that is possible, if yes then, please let us how we can do the same.
