Are you referring to the Kauai Marriott Hotel or to Kauai Beach Club? (confusing question because this is an integrated resort ---- with three timeshare buildings and one hotel building). The simple answers are: 1. If you are staying in the timeshare side ("Kauai Beach Club"), there are no particular Elite perks although you will receive room nights credit toward elite status and MR points for anything charged to your folio if you make sure your MR number is on the folio. 2. If you are staying on the hotel side ("Kauai Marriott Hotel"), in addition to receiving room nights credit toward elite and MR points for your folio, you are also eligible (as you are with all Marriott Hotels) for an upgrade to a room with a better view and/or a higher floor. At the Kauai Marriott Hotel, this usually means "Ocean View" rather than a "Garden View" (e.g., you see landscaping but not the ocean). As with all Marriott hotels, upgrades are based on availability. If you are going during a lower-demand season, chances of an upgrade are better than during high season. FYI, being a resort, there is no CL at the Kauai Marriott Hotel.
