Same-day or overnight: Kutch from Somnath
When a Madhuli taxi to Kutch should come back the same day, and when the honest plan is a night halt.
Do not promise the desert and Mandvi on the same arrival evening. The drive itself is about 9 hours to Bhuj and about 450 km. Double it, then add darshan, and you can see whether a return belongs in the same sunset.
Kutch is the far edge of a Somnath booking: Bhuj, the white Rann and Mandvi need nights, not a single sitting. A one-way drop and a car that stays are different jobs. Say which one you want in the enquiry so the driver is not guessing at the hotel gate.
The Innova or a group vehicle is the comfortable tool for hour six.
If you already have a hotel, send the area. If you do not, the desk can still run the cab. Hotel booking stays yours unless you ask for an area that is easy at dawn.
