I had a few questions about the platinum extras certificates. Is there any hope at all of getting the Regency Club Upgrade on a FFN stay (at Hyatt Kauai). I understand that to book ahead of time, it needs to be on a paid stay, but do they ever offer this upgrade at the time of check-in?

My other question is whether it is possible to use several certificates to get several different food and beverage amenities throughout stay. If I am staying 3 nights, can I use 3 certificates to get an amenity each day of my stay?

Thanks for your help!
