All right…im planning my senior trip and i need some help. The cities i wanna go to are Glasgow, Edinburgh, London, Amsterdam, Brussels, Paris, Madrid or Pamplona(need to know which one would be better), Barcelona, and Ibiza. i would like to know of some party hostels in those cities, great clubs and pubs and bars in those cities, and whatever other tips, tricks, and secrets you may have about those cities. Any help will be greatly appreciated.
