Ok, here is an analogy.
Went to check into hotel, it was a hotel on Latimer Sq, CHC.
I don't have a true credit card, Visa or Mastercard or AMEX or Diners, right, and they would not accept VisaDebit or Mastercard Debit.
Only had QCC and VGW, (VGW didn't have a lot sitting in it), QCC had though, so the check in person said they would accept the QCC which had Platinum on it of course, eh, so that was it.
Lucky I had Nzd$300 or so in it, Visso the Nzd$50 preauthorisation hold was ok.
On check out 2 days later, I had eaten a few things from the mini bar, so again paid with the QCC, that Nzd$50 took about 28 days to come back.
The mini bar snacks though was processed ASAP, 3 days and it went from pending to "hotel name-Christchurch-Nzd$19.75 or so.
Am going to NZ again in Jan, time to load up both QCC and VGW. AKL this time. A nights stay at that $$$ hotel next to AKLi airport. They have taken 21 days to return the QCC preauthorisation last time I stayed there, but its the only way to save having to stay in AKL CBD and get the Airbus at 3am.
Edit: has anyone tried to check into a hotel with one of those Aust Post prepaid Visa/Mastercard cards or the preauthorisation?
