Hi,

I'm planning a honeymoon to Hawaii and figured I'd splurge for first/business, but wanted to get the most bang for the buck/miles. So what's the best out there? I'd like to get something a bit better than the usual first-class seats that are common in domestic (oversized leather chair, basically).

Constraints:
Departing SFO/SJC/OAK
We want to go to one of Kauai/Maui/Hawaii, not Oahu, so arriving somewhere other than HNL (LIH/OGG/KOA) is preferable, although a transit through HNL for a better first-class experience is fine. Similarly, we'd be fine going via LAX or whatever for the same reason.
Looking to leave sometime after Labor Day in September.
I have about 100k miles on UA to spend, but I don't mind just paying for the whole thing or a combination of buying econ/upgrade.

Thanks!
