I would also recommend Resort Hoppa, it's cheap and direct to PP, you may have to wait for a short time while it collects it's passengers and there could be several drop off's on the journey, if you're lucky you will be the first drop which has happened several times for us. The fare one way is about 9€ (perhaps someone could confirm this), so not much more than the bus.
If you wanted to take the bus, the bus stop is situated at the end of the travelator (moving walkway), right outside the main exit. It is the number 1 and they are approx every 15 minutes into Palma, you would need to book to Placa Espania and there is a screen on board which shows all the stops as the bus approaches them. The fare is no more than 3€. Once in Palma you would have to go down into the main bus station which is underground and the PP bus (Transunion) goes from bay 5.
The bus route is very easy once you've done it once but for convenience and for somebody who is not very confident I would recocommend the direct route with Resort Hoppa or one of the other transfer companies. There's certainly not much difference in price.
Could any kind sole give me an idea how he gets to correct bus stataion from departures, thanks in advance 
I think hes a bit nervous about being on his own in a foreign country trying to find a bus,
