If it is too expensive anywhere, just DON'T GO!!!
I don't go, there are many other places and I have an excellent time.
And if you feel you miss anything, open your mind and you miss absolutely nothing!
Or : Go and stay calm. Dont have to be in a club every evening. Ibiza is nice enough to have a good holiday without Calvin Harris.
But I know ... you are sitting in Eivissa and look at the people ... the taxi run to the clubs start ... ok , lets go.
