I couldn't find definitive information on whether Udaipur Cabs Service offers shared taxi services from Udaipur to Kumbhalgarh. However, shared taxi services are not very common in India, especially for longer distances like the 86 km trip from Udaipur to Kumbhalgarh.

Here are some more likely alternatives:

* **Ride-hailing apps:** You can check ride-hailing apps like Uber Intercity or Ola Outstation for shared taxi options from Udaipur to Kumbhalgarh. These apps may offer ride-sharing options at a lower cost than a private taxi.
