Travel Delhi to badrinath and back was good.
Make sure requirements are clear and precise.
I asked for carrier on top with tarpolin and got it. Got cab for lesser price than other cab service. During journey time I called up driver at 11 am to remind to come to Delhi airport at 1 pm, which he came on time.
Remember to work with service provider like talking to them, calling driver if he had started or not atleast 2 hrs in advance as there is no app so that you get best service.
I think being nice with service provider and driver is key to get best service.
Driver was good, car was good. I gave 1100 extra for nice journey. Also gave rs 1000 extra to driver.
