We had 4 families who visited yesterday as we had bought coupons on GrabOne. The receptionist was so very rude with a frown on her face, when we presented the vouchers belittling us, asking for ID when it was obvious that the kid was a student. The vouchers are supposed to entice people to visit, get happy and impressed with the facility and visit again!!It was meant to be an enjoyable day out with family which started off with a bitter experience at the customer service desk. The receptionist was not even aware of the number of persons allowed on the voucher. Only 2 water rides were available on which 3 of the 14 people who came got injured. The staff were not even bothered to administer first aid. Food was good but too long to be served. A day of enjoyment turned soon into a day of “NEVER AGAIN EVER!!!!!!”
