Its kinda a miss for ibiza council not to have an official "everything you need to know about ibiza if not been before" landing page somewhere. (Taxies, hotels, prices, tipping etc etc)
I usually point peeps to spotlight as a central repo of info. (Like link in that post etc)
But Google search seems very hit or miss these days.
Edit: story behind the post is that someone on the group msg me and said, enjoyed 528, but the taxi was very expensive back to San an (50e).
I was like that's not right, and turned out had got an illegal taxi because they had no clue.
Thus made the post
