The Hawaii (concierge longhouse) will not be getting its rehab until approx 9/17-10/11. So if you are going before Oct. 11 then you won't be seeing a new room (or staying in that longhouse come to tink of it).
More info...if you are booked in a concierge room during those dates they are calling and switching guests to other resorts. Only the Tonga suites will offer concierge service during the Hawaii rehab.
