Can anyone fill me in on what happens on the last day of the tour...How exactly do you got back to barcelona from ibiza and approx what time ??? Is it worth staying an extra night there after the tour ???

I just came back from this tour a couple of weeks ago. There are many cheap flights from Ibiza to Barcelona. I purchased my flight on Vueling for 60 USD. I would say Vueling and Spanair have the most flights to Barcelona. There are also cheap flights to Madrid and London.
