It may be a bit harsh to say you will get a poor room... its the KBC in Maui for cryin' out loud!
I think there is a tendency among many in these threads to make the "room" or the TS company the central focus of visits to even the most exotic and exciting destinations when it comes to timeshare travel.
If you are going to "see Maui", and lounge by the fantastic pool, and enjoy the sun and ocean breezes, and walk the beaches... you will have a great time. We owned there for over 10 years BEFORE we changed to points; its a great location and we have many great memories that have nothing to do with Diamond, or Sunterra.
I'm also happy to say that I don't have any recollection of whether a kitchen countertop or the draperies were a little outdated while in Maui.
