When are you going?  If your honeymoon is in the winter, you should hit the South side, which catches more sun and stays out of the perpetual rain and clowdy skies that can sometimes hang around on the North side during winter.  But if your honeymoon is in the summer, hit the North side - the current changes, and the big waves start hitting the south side, so the beaches are calmer for swimming and snorkeling up North.

If you stay on the North side, remember that the hotels aren't directly on the beach, as most of north side is cliff face - I would consider staying near Hanalei Bay, at one of the large hotels there, or renting a condo - We stayed in Princeville in one.  It's worth renting a car so you can drive all around the island.  Defintley drive the 560 all the way around on the north side, it's fun :)

The south side is where you'll find your beachfront property hotels, and Poipu is very popular.  There's lot's of outdoor markets on along the drive from North to South, and you've gotta have a Puka Dog while you're down South, it's in the Koloa Shopping Center.  I'm absolutely drooling over one right now.  If you choose to go Ziplining (definitely recommended) hit the Princeville Ranch instead of the outfit on the south side - more jungle flying up at the Princeville outfit.

Also, hike Waimea canyon.  I couldn't squeeze this in on my trip, but I've heard it's amazing.  It's also called the Little Grand Canyon.  And if you can afford it, take a helicopter tour - I've also heard they're definitely worth it. Just note, there's not much nightlife - plan on exhausting yourself during the day, it helps make it an early night :)

I'm sorry this is so long, but I hope it helps!  Have a fabulous time!
