The ETA is end of April 2010. Here's the notice posted at MVCI.com, the Marriott Vacation Club owners' website:
"Please note, we are putting the finishing touches on a couple of restoration projects as we make improvements to the porte cochere and pool restrooms as well as create a new recreation and activity desk. We anticipate a completion date of April 30, 2010. The porte cochere and restrooms will remain open and operational, and we continue to be committed to providing the best service with aloha. Conditions relevant to these projects, including noise, should be expected."
We just returned from a great stay at the Kauai Marriott. The constrution was minimal and had no impact on our stay. I would not let the construction influence your decision on whether or not to stay at this resort. The staff was friendly and helpful, the location fantastic and the resort top notch.
