Was 'told' the other day by OH that we were going to Chester Zoo so began searching for vouchers or discounts to no avail. Found loads of 'kids go free' tickets but nothing for adults without kids. A final google, however, took me to a forum (I forget which I'm afraid) where someone suggested you could buy tickets from the information desk at Cheshire Oaks Designer Outlet (about 5/10 minutes from the zoo) for £9.99 as opposed to the £14.99 gate price. Worth a look I thought.
So we headed down there, parked next to the food court, ran in and sure enough bought 2 adult tickets for the zoo for £9.99 each! The next bonus was that while it added about 10 minutes onto our journey, when we arrived at the zoo, as we already had tickets, we bypassed the huge queues for tickets and went straight through the side entrance probably saving us about 20 minutes!
According to the lady on the information desk, the tickets don't have to be used on the day of purchase, but they did have an expiration date of the end of the month stamped on them so they seem to need to be used in the month of purchase. It should be noted that at peak times the gate price is £16.49 so there's a potential 40% saving to be had!
So just in summary-
Adult tickets for Chester Zoo for £9.99, available from the information desk in the food court at Cheshire Oaks Designer Outlet!
