going to honolulu at the end of feb. and beginning of march with my adult disabled daughter. she does well but snorkeling would be out, too complicated and does not swim well. pretty fair so will not be able to spend a lot of time on the beach. any suggestions to make this memorable for her? also any inexpensive to moderately priced restaurants that would be recommended.

Just returned from Oahu last night. I would suggest spending a day at the Pearl Harbor Memorials. The swap meet is a great place to buy souveneirs. We had fun just strolling around.

Make sure you take her to the Pearl Harbor Memorial. It is a must see in Honolulu. Also Waikiki Beach and I believe there is a place that she can maybe get in the water with Dolphins. I know sometimes they have programs for the disabled.
Also I recommend buying the book, The Unofficial Guide to Hawaii. There is a wealth of knowledge in this book. I am sure Waldenbooks or Barnes and Noble carry it. Make sure you check the copyright.
The Hilton Hawaiian Village would be a great place to stay. She would really get the feeling of being in Hawaii and it is right on Waikiki Beach. Have Fun

I've taken disabled kids to hanauma bay before. Instead of swimming with mask & snorkle, we give them buckets with clear plastic bottoms, or use big mayonaisse jars. She'll be able to walk into the water and see plenty of fish. Go early in the morning, wear a big sun hat, tee shirt and strong sun block and you should be able to stay long enough to have without getting burnt. Another fun thing might be to go up to the Pali lookout and walk to the right of the observation area. Face uphill, then have her hold out the bottom of her jacket to make a sail. The wind will propel her up hill. kids and adults love this! Visit the kahala Mandarin hotel and see the penguins and dolphins. It is free to just wander the area. Hilton Hawaiian Village also has lots of birds and animals on their grounds, and a great torch lighting ceremony and hula dances on Friday evenings.
Do you like sushi? Genki sushi on Kapahulu Ave is fun as the plates travel on a conveyor belt. The have some non-fish items as well...Miso soup, salad, ice cream... Catch of the Day, at the top of Kapahulu Ave is the same idea, but the plates travel in little boats on a water way. They have tempura, and dim sum items as well.
For seafood that is very reasonable, try Chowder House at the Ward Warehouse center. It is open for lunch and dinner. Sekiya is fairly close to Waikiki (across from Kaimuki High School) Very inexpensive, with a variety of food from grilled cheese sandwiches to local and Japanese favorites. "Sunset on the Beach" offers local music and old movies on a big movie screen on Waikiki Beach on Saturday nights. Free, but there are restaraunt booths offering food if you are hungry.

My first recommendation is to drive up to the Tantalus above Honolulu for great views. One of your stops should be the overlook in Puu Ualakaa park, which is a great place for a picnic or to watch the sunset. It is a beautiful drive (up Makiki Heights Drive to Round Top Drive) that offers the best views of all of Honolulu and beyond.

I would also suggest the Bishop Museum. It has displays of Hawaiian and Polynesian history and a planetarium, but also offers a full program of song, dance, storytelling and tours during the day. The Honolulu Academy of Arts, an art museum, is quite good and the restaurant there is considered one of the best lunch places on the island.

If I might ask, what are your daughter's abilities? How mobile is she? What distances can she walk, etc. This would help in answering your question.

If you have proper transport for your daughter, I'd think a day spent just driving the windward shore would be great for her. So many beautiful, and different types, of beaches to pull into and look at, stunning mountains and scenery. Stop at a "lunch truck" for picnic lunch plates and wait for the next likely beach park (we found lots w/picnic tables and bathroom facilities). We spent several very lovely and low-key days doing this on our trip.
