I don't know if you are still looking for an answer to this question, but I ran across an ad in Arthur Frommer's Budget Travel Magazine (page 99) offering a rate of $139 for the Courtyard Kauai good through 12/20/04. They give an 800 number or tell you to call your travel agent.
I also just looked up the hotel on the Marriott website and picked random dates in June (after I thought it was supposed to be open) and they asked me to pick a different hotel on the island.
I hope this helps some. Maybe someone else knows more!
