Can't see a deal on here for this so I thought I would post one. Basically its a win win situation for you and for the Eden Trust. When you buy your tickets online instead of just normally paying the daily admission price, you choose to make the Eden Trust a donation of the same amount, you will be able to exchange your admission ticket for an annual pass to Eden. So buy once, visit as many times as you want! Sign up to the newsletter and look out for upcoming events.
