Hawaii – doable for 5k?

Looking to honeymoon in Hawaii Oct 2025 for 1 week, flying from MSP.

We would want to island hop to visit the national parks on Big Island and Maui for sure. Also would like to stay in relatively nice hotels a couple days for beach/pool lounging, while also being able to explore the area. Basically, a good mixture of relaxation and exploring!

Is this possible for 5k if this includes our flight budget? Is this possible for 5k without including flights?

Recs on where to stay, how to get to the parks, things to do, etc!
