ATD has Discovery Cove on sale at £507, this was 2 ultimate swims and 1 ultimate non swim. I found a cheaper place on the web and they price matched down to £484. I then got a call saying that because my son is over 2, I had to purchase another non swim. They had not added this at the original purchase. I then got a call later on saying because it was there mistake they have arranged for my son to get in for free !! I am very happy with them for this, I didn't even ask for them to do this.
