Advice;
Sticking to Eivissa town area of your older is generally a good move, but do visit san antonio.
You can get taxis and busses anywhere you want.
Tell the fat squinty con artist in Eivissa to piss off if he approaches you.
Be nice to Snakeman he's a good guy, and knows everything thats going on.
Pacha is a must and the harbour area bars are excellent.
Get a hotel in walking distance with a fridge as you'll want to stock it up.
If you see a shot away looking guy who looks like Catweasle thats Alistair Lougue ( Alistair "Empire") he knows everyone -say hi he's a hoot. Go to one of his parties.
Dalt Villa of Course
Get out of town to:
Underground
KM5 to take a new friend for dinner
Blue Marlin
L'Elephant
Kumharras
Sol Den Serra
Bfor Ibiza sushi - mmmmm drroool
Atzaro for dinner
El Ayoun as above and stay -
Match Bar - it works like it says above the door!
and most of all go to:
Teatro Pereyra until it closes, great live music cool people, best sax players Rafa Garces from Cuba and Dominique de Larrard on the island, and catch Laura Fowles mixing it up with the house band between saturday El Divino Hed Kandi sessions (which will be moving this year). Be nice and interesting and someone will invite you to a private villa party or two - unless your renting your own in which case invite some strangers back its good to reciprocate its good karma.
Get out and about to as many places as you can during the day and hire a car and just go roaming up to portinax and along the coasts. Find Cueva de las luces (NOT can marca) and jump in.
Sant Carles
San Miguel
Go to formentera
Salinas - chill with Jon Gray at Sa Trinxa
Kiss a stranger or two at bora bora on playa den bossa.
I've got to see the new places down there too.
Try to go on full moon and get into an Azuli party - usually at Sol Den Serra but they move about.
If you're after more than a tan, get nekid with the 'lads' on Es Cavallet if its your thing or not, its up to you.
Get lost as much as possible.
Its Ibiza - at all times stay calm, don't do anything you don't want to..
