Are you planning to go further or will you stay in Hvar? I also went there this way, but it was really worth it because it is so beautiful. I was traveling with my family and I was also looking for minivan options so that we could travel in one car. I found different classes of Split taxis to choose from on the GetTransfer website and booked one of them in advance. We were very lucky because the driver spoke English and we understood each other without any problems. I think you can indicate this important point in the comments when you book a transfer, for some reason I completely forgot to do it.
