As a former student and now A licence holder, that reseearched all the best options for a UK student in europe, I took my AFF at the FreefallUniversity.co.uk and have been back since then to complete my consoles and just about to book to go again, I would highly recommend the FF Uni at Lillo.
It all depends on whether you just want a holiday that you can skydive on, or if you wanna skydive and fit in some holiday. I highly recommend the FFU for students, Barry "Yoda Master" Maple was the most conscientous, considerate, down to earth, friendly & experienced instructor I have met, & a master rigger too. Seriously dude, if you are at student status go here, the landing zone is as safe as a fussy b'stard like me would want, you dont have to deal with the wind that Empuria has been known to have (Student Yes!) and there is plenty to do off the DZ if you care to take yourself away from all that sky & fly, last time I went to lillo I also learned to snowboard (on real snow) in between the best jumps and the crew there are friendly & fantastic company, everyone is willing to care and share their experience and thoughts, there are a range of options too, it was warmer, the skies were clearer and it was cheaper than the UK including accomodation, couldn't recommend them enough go there now dude and fly, www.freefalluniversity.com
Happy landings
