Is there any places we're missing out on that we should go to?? We're staying in Playa d'en bossa
Plenty but it's only your first trip and sounds like you're keen on your clubbing ...
Sun 31st July – arrive about midday. Get there probably chill by the pool and go Space that night. What time should we get there for?
Personally I can't spend a whole Sunday afternoon and night at Space & never go before 1am - but that's partly because it only really kicks off properly from 2 and 4-5 hours is enough for me .. not least 'cause I like to drink steadily, not binge up and arrive drunk, especially with red bull & vodkas costing 15Euros a throw in there ! Think you can get in earlier for cheaper but reckon if you wind up drinking they've got you one way or another

Think you can get in early then get a pass-out and return later - someone else can likely help you on that.
Mon 1st Aug – Pacha for SHM
Breathe in hard - it's rammed to the point of being ridiculous that night at Pacha !! You can see SHM too in the daytime in the open air on a Wednesday (4 or 5pm - midnight) at Ushuaia for a fraction of the cost if you buy online through Spotlight, and can actually move as much more space.. prefer a (different) night at Pacha to an Ushuaia party personally, but for SHM it might be something to think about.. you could then do San An bars on Monday instead and Cocoon at Amnesia on the way home (it's half-way to PDB)...
Best daytime party on the island's at DC-10 near the airport on Monday tho' (Circoloco) .. how to choose ?!!
Tues 2nd Aug – go to a few bars (which is the best area to go?). Aim to get to Café del Mar to see the sunset
PDB has loads of daytime bars and beach clubs - if you like it snazzy, try a sunbed at Nassau or Sands. Otherwise grab a spot near one of the others like Delano/Bora Bora etc.
If you go to San An, get up there by 6.30pm. Mint Lounge, Mambo, Cafe del Mar Savannah & Kama Sushi are all in a row literally steps from each other so you can pick which one you like the music /food best.. if you arrive early you'll be able to book a table at one of them for later if you want to eat when you've seen the menus.
Earlier on, it's much nicer (imo) a short stroll up the coast (along the prom, sea on your left) at Kanya, Sunsea Bar, Golden Buddha and Canguiri. Kanya has a pool and cocktails are by the jug. Golden Buddha's probably the nicest vibe and is a bit further along from Kanya round the corner set back from the beach at Es Calo d'es Moro. Canguiri is a bali-bamboo cave-like affair with free wifi and Mojitos for 5Euros. Sunset's great from anywhere round there.
Wed 3rd Aug – Zoo Project
Fair enough. Would choose DC-10 on a Monday over Zoo & do SHM @ Ushuaia on a Wednesday if I wanted to see both, meself !! but that's just me being biased ... Not everywhere sells tix for Zoo. You can get tickets at Tantra in PDB and either Pussycat or Bunker in San Antonio have tickets (according to their flyers).
Carnival @ Sankeys in PDB is their underground night and has had some good reviews - apparently you can get wristbands for free entry before 1am and might make a good follow-on to Zoo or "daytime SHM".
Thurs 4th Aug – chill out in the day, our flight is 2am. Are there any nice restaurants we could try?
Try the Fish Shack in Talamanca (just north of Ibiza Town) for an early dinner. You won't regret making the effort to get there !
You could also be proper ravers and go to Sahsa - Never Say Never on 4th August @ Ushuaia, which finishes at midnight .. could leave your luggage with the hotel there, I'm sure and get a cab straight to the airport in time for your flight, as it's only 5 minutes away in a cab
So what do you think? Are we missing anything that would be worth going? Are we not doing enough etc
