Question: is ushuaia strict with id?
Answer: For most venues, eg super-clubs like Pacha, Ushuaia, Hi Ibiza, Amnesia or Eden, smaller clubs like Octan or Bora Bora, other daytime venues like O Beach Ibiza or Ibiza Rocks and also for all boat parties you will need to be 18 years old and often show an ID. These rules are quite strictly enforced.
