Yesterday, Ms Schnor said they were still upset at the "blatant" way the resort changed their minds.
"Offering one thing, on their own initiative, then adjusting the same offer, then suggesting, for them, a cheaper alternative, then going back on their word altogether."
Ms Schnor said she wanted to speak to whoever owned Huka Lodge.
"Four days cost us a whopping $23,000 - excluding drinks or extras. These rates beat those of any luxury hotel in the world.
"I left New Zealand with a bitter taste in my mouth."
The family were looking at their legal options.
Last week, Huka Lodge general manager Louis de Bievre called the situation "hugely regrettable" and blamed a miscommunication between Mr Schultz and a staff member for the disagreement over the refund. He said Huka Lodge was no longer using the company the driver worked for but did not respond to questions about Ms Schnor's concerns about the refund.
