It's a warehouse store in the US. They usually have good deals on tickets for different attractions. I'm not sure if any of that can be accessed in New Zealand.What's Sam's Club? I'm from New Zealand, don't think we have that here! Prices sound good though!
If you have a Sam's Club membership, they have a July 4th special right now where you can get 3 day passes on the Sam's Club website/app for $193.00+tax for adults and $179+tax for kids.
