So you wouldn't recommend HHV?
Well, I wouldn't say that, but I did have to go back & read all of your previous posts in this thread. My comment was based strictly on post #51 and the assumption you acquired MKO/MK1 thru II. Now I realize that you plan on paying cash/renting a TS for the Marriott stay, or somewhere else, and do not have the 3 nite stay secured yet. Therefore, either HHV or MKO/MK1 would work.
Here are some comments:
MKO/MK1:
1. Quieter and more relaxing than HHV
2. Rooms are bigger
3. You'll have a washer & dryer
4. Parking is free, UPDATE: Free only if you exchange in, otherwise you have to pay

5. Less walking
6. Easier access to grocery stores
7. Less traffic
8. Closer to the Aulani
9. Maybe closer to the airport
10. Less crowded/people
HHV:
1.
Do Not rent a room in the Kaila Tower, it is a long, long walk from everything. The tower is a mixture of hotel rooms and TS's. The pool is small.
2. The Grand Waikikian is the newest tower next to the Lagoon tower. Although it's newer, it's not as convenient to the pools, lagoon, ocean, restaurants, etc as the Lagoon Tower.
3. If you stay at HHV, get a 1 or 2 bdrm TS in the Lagoon Tower, you'll be close to everything.
4. Good for Waikiki & Honolulu site seeing
5. In January, you can go downtown and see the XMAS tree lights & decorations at City Hall, which are cool and your kids will enjoy it. We'll go see them again this December.

6. You can take one of the hop on/off tour, which was interesting. We took the tour that went to Diamond and beyond.
7. You can go to Hanauma Bay, the Aquarium, & Sealife Park.

8. It is nice to walk along Waikiki Beach.
9. NO grocery store, except for local ABC store (expensive) or Foodland at the mall (don't go there, we did).
10. Parking is expensive.
11. Traffic is a bitch.
12. No barbeques
13. Playstations and I believe free DVD's?
14. Waikiki Beach
15. It's closer to shopping if your into that, but I'm not and I'm still not sure what people shop for.
If you do decide to stay at HHV and you've never stayed on Waikiki, you can probably use more than 3 nites, but it will give you a taste.
