Hi annanicole0,
When come through arrivals at Corfu airport, your rep will be on hand. Tell either he or she that you are making your own way to resort and they will tell you the details of your apartment, i.e room number etc.., the taxi rank is just to the left when you come out, but I'm sure if you have a chat with the rep they will talk to the taxi on your behalf to make sure you get there safely.
Hope you love Arillas as much as the rest of us, I'm sure you will!
