Wet ‘n’ Wild Sydney in Prospect has received mixed reviews from some two million visitors since its opening last month.
They include Glenmore Park resident Alison Adams and Rochelle Coppini, 19, of Blacktown.
Mrs Adams said she regretted buying gold season passes for herself and three other members of her family.
‘‘We bought them online back in November and they were supposed to be mailed to our home,’’ she said.
‘‘That never happened despite phone calls and emails which received no response.
‘‘We ended up driving to Wet ‘n’ Wild on Christmas Eve to pick them up and, when we asked to buy a fifth pass, we were told they were no longer available.
‘‘Now every time we go we have to fork out $55 for our five-year-old which makes having an unlimited entry pass a bit of a joke.
‘‘They charge $10 for the lockers even though we were given the impression they were free if you bought a gold pass,’’ Mrs Adams said .
‘‘There’s nowhere near enough shade or seating and the fact you can’t take your own food makes it potentially a very expensive day out for five people.
‘‘It’s disappointing given the expectation that was created.
‘‘They have quite a bit to do to improve things.
‘‘I won’t be buying another season pass.’’
But Rochelle Coppini — who has visited the water slide park twice with her friends — said she loves it there.
She said they each paid $70 to enter and were at the park from 4pm to closing time at 11pm.
They had no complaints.
Ms Coppini wants more restricted ‘‘fast-track’’ ride passes to be sold, saying she doesn’t mind paying an extra $50 to avoid a long wait.
‘‘I don’t think it’s expensive,’’ she said.
‘‘It’s better than the park at the Gold Coast and Jamberoo in Wollongong.
‘‘We don’t find the price of food expensive or didn’t suffer any bad effect from the rides as we followed the instructions given by its friendly staff.’’
A Fair Trading spokeswoman said a business had the right to charge a fee for services they provide but a consumer must be made aware of the cost involved before they agree to the service.
She said the cancelled New Year’s Eve Festival was organised by One Cube Entertainment Pty Ltd.
‘‘As at January 20, NSW Fair Trading had received 81 complaints about One Cube Entertainment Pty Ltd and the cancelled NYE Festival,’’ she said.
Consumers who have concerns about not receiving a refund for the event should lodge a complaint with NSW Fair Trading, she said.
Advice is available on a dedicated hotline: 1800213428.
To lodge complaints go to www.fairtrading.nsw.gov.au or at any Fair Trading or Service NSW centre.
Wet ‘n’Wild Park spokesman Darrin Davies said only a small percentage of people were unhappy with the park.
He said there were no plans to reduce the entry price or locker fee or the cost of special rides and food sold in the park.
Mr Davies said only visitors with a special diet would be allowed to bring their own food into the park.
As far as complaints on social media sites, he said there were about 10 negative comments from about 50,000 comments.
