Going to Arabba in one week. Flying on to Venice, Marco Pol. We are two families (4 kids). Since we're not arriving and leaving on the weekend, the transfer service wasn't an option. Instead we asked the hotel to arrange a private transfer with minibus. They charge us €500 for a roundtrip. Think it's very reasonable. Getting two cars would be about the same and not having to drive, mess with picking up and returningthe car and be responsible for a parked car is BIG plus. We used to hire cars before but tried to private transfer a few years ago. Haven't looked back once.
