Hawaii

My dad is giving me and FH his timeshare for a week and we have a choice of these resorts:

Kauai, Hawaii
Marriott's Kauai Beach Club
Marriott's Waiohai Beach Club

Maui, Hawaii
Marriott's Maui Ocean Club
Marriott's Maui Ocean Club - Lahaina and Napili Villas

Kapolei, Hawaii
Marriott's Ko Olina Beach Club

Does anyone have any experience with these resorts or can you give me details about Hawaii in general? I've checked Trip Advisor but the reviews are all so mixed. Right now we're leaning towards Marriott's Kauai Beach Club which is the #1 Hawaiian honeymoon hotel per Wedding Channel. TIA
