i hate people who spend half their time on here just slagging the west end. It has its purposes and despite what some might say i and a lot of others have never seen a fight or people being sick on each other. In fact the most i've seen is a guy being thrown into a police van, nobody paid any attention and it was over in 1 minute.
the west end has a purpose for a lot of people visiting ibiza, its a place to start the night with some cheap drinks, socialize, talk about the day etc and mingle before moving onto a club and paying silly prices for drinks.
the bigger bars also can serve as a decent night out, especially if your breaking up your holiday and not going to a club for 1 or 2 nights.
thats what we do generally when we go, we will go down to the sunset bars, watch that at coastline etc, go back to the hotel, play some cards, get ready and go out to the west end, do a lot of the bars there, then for 7 or so nights of a 10 night holiday move on to Pacha, Amnesia etc and stay there until closing.
Considering we go out at 10pm there is plenty of time to spend in the west end and still have a proper clubbing experience in ibiza.
