Yeah a load of us worked out there this summer, its ridiculously easy to get a job there 'cos staff are always coming & going, although best to get there early for the better paid ones, the main jobs are promo, ticket selling, bar staff & selling laughing gas! Most bars & ticket places want you 7 nights a week there & they work you to death, the other jobs are more flexible, I worked at bar plastik, 8-6am, Quit there after a couple weeks but some nights we were earning 70-100e mostly from tips, didnt even really need to work the rest of the holiday after that. Total contrast from the ticket sales job two of the girls had where they worked entirely on commission & some nights they came out with 4 euros each after trapesing round for 4 hours!!! If you do ticket sales make sure you get a basic wage as well. The funniest job we did was promo street parades, had to dress in these mad camouflage print outfits & cover ourselves in camo-face paint & strut down the beach with music blaring out shouting out the names of the dj's etc, plus could sell tickets at the same time to make a bit extra, only got 25e a day basic for that though.
The best privately owned apartments to live at are the Ricar & Azul, dirt cheap & you might even get air con if you're lucky.
