Hilton Queenstown for example only provide continental. It's $10 extra to get the full breakfast.
That's good to know actually, as I'm booked into the HQ this coming August. I had been musing that as a Diamond I'd wasted money booking the 'bed and breakfast' package, but possibly I would have had to stump up an extra NZD$10 anyway? Hope the AUD doesn't tank before I get there!
