Honeymoon in Hawaii - need recommendations

In that time frame, it's hard to do all the islands.
I would suggest flying into or out of Honolulu and spend the front end or back end going to Pearl Harbor and other things you want to do on that island. Keep in mind, that is the busy city and not the relaxing island so I would spend a day or two at most there.

We went to Maui and from Road to Hana to luau to snorkeling Molokini and with sea turtles we enjoyed our time on Maui.

With that said, you can't go wrong on the other islands either but if you try to do to much you will end up wasting a lot of time when you can stay on one island and do everything you pretty much want.

Hawaii beaches are a lot different than going to Florida beaches and I would say you would spend very little time on the beach itself. The surf can be very rough in most places but your hotel on the beach will have plenty of amenities as well.

I've never been to Kona or Kuaia but the Volcanos National Park is on Kona.

Kauai is spectacular. I don't know that there are any active lava flows currently, but that is subject to change all the time.

shark cage diving is West and north Oahu also. Oahu has good snorkeling at Hanauma Bay, no active lava on Oahu

If you are up for a hike, check out Stairway to Heaven. Amazing views, not for the weak at heart!

Flew in to Honolulu for my honeymoon. Only stayed there two days to check out Pearl Harbor and Diamond Head. We then flew out to Maui and that's when the real relaxation started. I was over Honolulu pretty quickly, but it was worth it to see Pearl Harbor.

When in Honolulu, hit up House Without a Key. Get there about 30 minutes before sunset and enjoy.

How much does it cost to fly from island to island and how much hassle is it? I am assuming I would have to rent a car at each location? Im struggling because there is something I want to do at each one lol.

So far I have planned.
--Oahu - Pear Harbor and Shark Cage Diving (2 days, can I do both in one day?)
--the Big Island (not sure how long to stay but I already have an accommodation lined up for one night)

--Can I squeeze in both Maui and Kauai?

We spent 5 night in Kauai followed by 5 nights in Maui and really enjoyed it in that order. We did a good bit of on the go adventuring in Kauai and then kicked backed and relaxed in Maui.

Lodging: the grand Hyatt Kauai and Andaz Maui. Both fantastic, and again hit the spot for our activities. Grand Hyatt does have a few more families but since we were out and about most of the time it didn’t bother us. The Andaz is was very relaxing and chill.

Kauai: helicopter tour is a must in my opinion. Blue tours was who we used I believe. We also did some atv riding - they take you on some trails including the famous Jurassic park scenes. We did a boat ride to see the napali coast which was beautiful. Also spent a day up the north of the island. Went to Hanalei bay and hiked down to queens bath. Other than that, did a bit of snorkeling here and there and of course, went to a dinner luau, even though everyone said not to. we made friends at it, but it was indeed pretty lame.

In Maui we really just relaxed at the pool and beach. We did do a bit a snorkeling, but other than that really just enjoyed relaxing. We did stumble on to a nude beach...totally not anyone that should have been naked to see. We wanted to do the road to Hana, but just didn’t make it. I’d probably look into that if I were going back.

We rented a convertible on both islands and I would recommend that highly. Also, go get fitted for some snorkel mask and fins and bring your own if you plan to do much snorkeling at all. Totally worth it. And bring the go pro! Both stunning places to see.

Pearl Harbor closes earlier than you’d think on weekends. We cashed in some Hilton Honors points for six nights in Honolulu. The Pearl Harbor area is near the airport so we thought it would be a nice last thing to do before flying home. Flight was around nine so we were going to get to the airport around 7:30. Rented a car the last day and drove around to a few different places. Got there around 3:45 and we’re told the last ferry over was gone but we could see the museum. Kind of sucks we missed that. So if it’s a must see, plan ahead a little. We could have grabbed a hotel shuttle or taxi any day we were there but didn’t think about it being closed before 5. Especially on a Saturday.

I went ahead and booked a Saturday to Saturday in December at the Hyatt Kauai.

That's not too long right? I'm not a huge beach lounge person but there appears to be enough activities.
