Koa Kea or Grand Hyatt for honeymoon in Kauai 🌸

We are trying to pin down details for our June honeymoon in Kauai and would love some opinions! Budget is 8-10k.

For hotels I’m mainly looking at the Grand Hyatt and Koa Kea. Has anyone been to either??

We may only be able to go for 7 days, but are hoping for 10 days. If we do 10, I was thinking we could stay at a resort for a week and do a lower cost Airbnb or vrbo for a few days on a different part of the island — maybe the north shore. Any tips on that would be amazing.

Thanks so much for any suggestions 😊
