I also am looking at this Express Deal but for an earlier date in June. I have come to the conclusion that it is for the Royal Hawaiian because it is the only one of the three 5 star hotels listed (Royal Hawaiian, Trump and Halekulani) that charges a resort fee. If you do book it, could you let me know what hotel it turns out to be? I cannot book the Express Deal until after June 1st because I am waiting on a promotion code from Priceline that was given as an incentive for booking a cruise with them (but only available 3 weeks before the cruise date).
