Ok, here goes ..............
I recommend seeing Pearl Harbour. It's really worthwhile to visit and pay respect. We caught a bus on Kuhio Street, it only cost us about $2 each from memory. Took us direct to a stop right at the centre. We took advice from others and went early, however so did the tour buses! So, we ended up in line with about 300 other people from the tours waiting to but tickets! I'd go a bit later if I were you to avoid the lines and crowds. The tours move through at a reasonable pace, so by the time you get there the crowds should have thinned out a bit. You can take a lei to place at the memorial if you like.
A hike up Diamond head is a must! Wear sturdy shoes, pack light,take water! Just take your time. If I can do it anyone can! The view is so well worth the climb!
Waikiki is very touristy, has all kinds of shops and hotels everywhere! There's ABC souvenir shops located on almost every corner. They're great for purchasing sundries, - (film, batteries, shampoo, snacks etc) - a bit like an Hawaiian 7-11 with T-shirts!
We had a meal at the Tiki Bar on Waikiki Beach and really enjoyed it. It's on a balcony overlooking the strip and beach. I had a decadent dessert there!
The "International Marketplace" is a bit like an outdoor bazaar with stalls. It has a lot of the same stuff over and over but is fun to walk through. In the centre is an outdoor bar that has hula dancing and live music at night.
One of the highlights of our visit was the Polynesian Cultural Centre. I strongly encourage you to go there! A fabulous day out. We bought the "Ambassador' package, which included the day tour, the dinner - (or Luau if you so choose)- and the night show; "Horizions". We chose the dinner in the restaurant since we'd already been to "Germaine's Luau". Which I also highly recommend.
We also spent a week on KAUAI.
This island is absolutely BEAUTIFUL! It's not touristy as is Waikiki, is easy to get around, even us Aussie's who had never driven a car in America - (on the WRONG side of the road! lol) - hired a car and got around with -( mostly!
) - ease! Waimea Canyon is a must see, they call it the Grand Canyon of the Pacific and it's wonderful! Princeville is also beautiful. Anini Beach is also lovely to spend time at. Hanalei is a lovley spot and has shops and eateries. KAMOKILA HAWAIIAN VILLAGE is worth a vist to see how the people lived in days gone by. Go snorkling at Lydgate State Park, a lovely lagoon type of area on the beach enclosed by a rockery and you can see all kinds of fish. Safe for kids too!
We stayed at the RESORT QUEST ISLANDER ON THE BEACH at KAPAA on the east coast of KAUAI. We had no complaints and enjoyed our stay there. I'd happily recommend it to anyone. The COCONUT MARKETPLACE is right next to the resort and easy access for shopping and meals etc.
Hope this is someway helpful to you, Joe. If I think of anymore to share, I'll post again.
I just LOVE it and am keen to return!
I totally recommend KAUAI!
Waikiki is fine for a first or brief visit, but it's very commercial and busy and geared to the tourist for sure! But ... it was fun just the same.
