I'm hoping to take our youngest daughter to London Zoo this Easter and have been looking at buying tickets online. ZSL are recommending buying fast track tickets to avoid queuing to get in. They are £3.50 each more expensive and I somewhat baulk at paying extra because they haven't got their queuing system right. I'm going to buy the tickets online rather than at the gate so just wanted to know whether its worth paying this amount (and swallowing my pride!) to avoid standing in line for hours with a 7 year old. Does anyone have any experience of this? Thanks
