I dont think that there is a direct bus from Girona airport to Platja D'Aro. A previous post has said that you can get a Bus from Girona airport to Girona city www.sagales.com and then Bus Girona city to Platja D'aro www.sarfa.com but arriving at 10pm i do not know if local buses will still be running.
How many of there are you, as its around €50 for a taxi to Platja D'Aro from Girona airport which should take 4 people.
hope this helps
If possible, take a taxi, it's about 30 minutes and 55 EUR.
