You could probably walk to Caleta from the airport... no, seriously, it will cost about 10 euros - Caleta is right next to the airport, you'll see your hotel as you're coming in to land

Thanks for that.

Do you think its best to book it before or when i get there??

Whats the shuttles like?? I know they are cheaper but do we have to que??

Just jump in a taxi when you get there - there should be plenty of them as you come out of the airport building. For the distance by taxi to Caleta, I wouldn't bother faffing around with shuttle buses, might as well just get a taxi. Coming home, just get your hotel reception to order a taxi for you.
