I've booked Marriott Kauai resort for 7N using rewards. Since I have 2 kids (8 &2) I am concerned with the room space (450+ sq ft) at the Kauai resort. Koloa standard award also comes with similar sized room. It would be nice if we could get upgraded to the villas since they have at least 800 + sq ft space.

With Marriott Gold, what are my chances of upgrade at Koloa landing resort to a villa? Thanks in advance for your responses.

Edit: OK, I changed my reservation from Kauai resort to Koloa landing studio. Seems like a hit or miss with upgrades for Gold. I am taking my chances.
