Hi ~travel!

My partner and I are going to Oahu for a ten day holiday at end of October. Neither of us have been there before. We are looking for advice on what to see, eat, do. We have a rental car.
We'd love to see some less popular nooks of Oahu without angering the locals.

So far we have to do:

• Pearl harbor museum, USS Arizona.
• Surf somewhere we can both enjoy. I am experienced but in intermediate paddling shape. Partner is a novice. Trying for a couple hours' AM paddle out for a few days. Beach, point, or rock reef breaks.
• Drink a Mai Tai. Where is the best bar on the island? Posh or dive? We like dive bars but aren't afraid to splash out for a fantastic experience.
• Attend a luau. Who's got the best roast swine? Removed this on the advice of commenters, also very expensive after looking into it. Will go eat at a few food trucks instead!
• Day hikes. Where are the good trails?
• Non-surf watersports. Can't afford marlin fishing with our budget but snorkeling, diving, or sailing are realistic options.

Anything else? Some of the best travel suggestions have come from strangers in hostels or bars - probably also Tildes. Thanks for reading everyone!

edit: for brevity

My lease is ending within the next two-three months and I have been trying to plan my next steps. My goal has been to buy a house (and hopefully coincide with my lease ending) but the more I have been looking at inventory, the more I have been hesitating about that commitment. I currently am a full time remote worker who can live in any US state at any given point.

I found that I can find a short term rental (60-90 days) in downtown Honolulu and am finding myself increasingly interested in the prospect. I have never visited Hawaii, and while I was recently married, we never actually went on a honeymoon because we are saving for a house. The rental I would choose would be ~$2300 a month, fully furnished and utilities included. I of course would have additional cost to consider, such as needing to put all my furniture in storage and paying rent on the locker. In addition, I would not have my car so I would need to find a decent place that is walking distance to life necessities.

This option would not make me broke, but it would cost me additional money. If I bought a house now, I would probably have to hold off on any big vacations for awhile, and Hawaii was on our list to go to in the next 5 years.

So just curious, what are your thoughts? Would this be a good way to spend my winter or would the burden of not having a car be difficult in Hawaii? Any other things I need to think about?
