Where are you flying in from? What are your general plans? Are you going to Plitvice Lakes? In June, we vacationed with a large group and went out every day, though not everyone went with us. We used the transfer services of https://gettransfer.com/en/directions/croatia. Every morning, we booked a transfer with GetTransfer for the next day, and everything was perfect. They have cars with different numbers of seats and levels of comfort. Sometimes there were five of us, and other times there were seventeen. We did what we wanted because some of us also wanted to relax on the beach. By the way, where did you stay?
