My mom and her husband are going to Honolulu in April for 2 weeks. She is looking for suggestions from anyone who has been there what is a must to do. This is their first trip like this. Because they are "older" they probably won't be doing and scuba diving or snorkeling. I think they are looking for for a luau(sp). Someone mentioned something about one called the Shower of Flowers.  
If anyone has any ideas that I could give her I would really appreciate it. She also wasn't sure if she should book things now or when she gets there.  
I don't think they are planning on renting a car.  
 
Thanks
