The Tunnel nights were at Privelege, the same club that holds Manumission - but they may have moved this year so make sure you check before you go.

Personally I would suggest going in to Ibiza with an open mind musically, the first time I went I came back with a massive appreciation of other genres, especially funky house.

There isn't much hard trance on the island, perhaps try the Godskitchen nights as well as the Tunnel nights.
