Read your deal with Maui VERY carefully.
I rolled up to collect a motorhome. Presented my card for imprint [which I have done in every place I've visited] and was told I had to have $7500 IN THE ACCOUNT. I explained that I had this amount easily covered in another account. They would not accept that account. CONSEQUENCES - I had no choice but to cancel. They have now said I cancelled, therefore my fault. I am now out of pocket $1200, I had to get extra hotel rooms at high cost and plane fares Darwin-Melbourne, MANY more dollars.
A representative of Maui told me TOO BAD! Go away. He will not give me a name for further up the chain of command to plead my case but says he has no power to help me.
