I dont think many 5* properities in Hawaii etc have elite programs. I believe the OP somehow misunderstood the hotels nice offer and asked for something that was not offered. I never understood people emailing, faxing, telephoning etc hotels for "upgrades" unless they are elite with the hotel or are celebrating very special and cannot afford to pay for whatever reason (ie just married, new child etc). Since the traveler is staying/paying for 12-14 nights at 5* hotels in HI, one might conclude she is a lucky and/or deserving person fully able to pay for luxury. I hope she enjoys it.
The hotels love to sell upgrades in HI and have a zillion room catagories to offer, each for more money. Think of it, if the hotels gave away all the upgraded rooms for free in advance, they would have nothing to sell those who arrive and are willing to pay for u/g. Ditto for the airlines.
