Hawaii for Honeymoon

Hi everyone,

I know there is a lot info on Hawaii but I was hoping for a more recent review of Hawaii. I am undecided as to where to stay in Kauai and Maui. From what I get Kauai is more of a relaxed island than Maui. I need some help with Kauai. As for Maui I am not sure between
Hyatt Regency
Westin Maui
Four Season
Fairmoint Kea Lani.

I want a fun place but something romantic with a nice setting and nice pool area where I can just relax in a cabana. I I heard the Hyatt has to many kids and dont want them running around the pool area leaving food behind, I am not looking for to much crowds. However I heard Hyatt in Maui has a nice mall area and nightlife nearby. Is this near to the other hotels? Which hotel has a nice beach area as well?

Any thoughts, suggestions , pics or reviews??
