I went 4 years in a row now and I am 28....You will have nothing to worry about as far as age..... Definately do -Manumission on Monday then straight to Space for afterhours (during space go to bora bora across the street for a few hours and then back to space) -A beach called Salinas (the most beautiful beach in Ibiza) -don't go out until late (3-4am) things don't get good until then -Good Pizza at a place called "el pirate" at the port of Ibiza (Italian owned) Avoid -stay away from the foam party at Amnesia...the bubbles they use are so strong you will feel sick, plus they play 80's music while shooting the foam (buzz kill) -Getting cabs are going to be a pain in the ass (from the clubs) -You will be hounded to have a drink when you go to the port of ibiza (I usually make up a language and they leave me alone)
