You risk to wait very long until the van will depart at that hour. 1,600 B for a return transfer to Karon is very reasonable; book it! If you book at the airport expect around 1,000 B to Kata (one way!).

Unfortunately, in Phuket taxi and Grab doesn't work as you are used to in BKK or elsewhere in Asia. If you expect significant savings by using Grab or taxi compared to the inflated fixed rates dictated by the local taxi mafia, you will be disappointed.
