Take your birthday to the next level with pure challenge, fun, and adrenaline!
We know lining up the guest list for a birthday is never easy, so don't worry: you pay when you book, but the number isn't locked in. Write to us at alcorcon@sparkisland.es or tell us on the day and we'll adjust it, with a refund of the difference if you end up being fewer people (minimum 6 participants).
