Welcome to FlyerTalk,

As others have suggested, there's quite a bit of information here in the archives that might answer your questions about Kaua`i and the Marriott.
For example, if you go to the Marriott Forum (
click here) and search the archives for "Kauai", a number of threads appear. You may also want to take a look at
www.tripadvisor.com
The FAQ and archives for this forum also contain many threads on Kaua'i, including where to dine and what do do.
