Hawaii

Someone finally chronicled our Hawaii vacay!  Check out Jenna's post and I'll remind Mike that he needs to get around to doing our Hawaii post :)  He tried to tell me tonight he wasn't aware of his responsibility.

Hawaii Advice Please

I need the advice of all you experienced Hawaiian travelers.  There is a dental convention in Honolulu the end of April and Mike and I are considering making a family vacation out it.  What I really want to know is where you recommend staying (hotel vs. condo/house) and would it be best to stay in Honolulu or somewhere else and rent a car?  Keep in mind none of us have been to Hawaii and this would be a family vacation.  I want to be able to hang out with the kids at the beach or pool while Mike is in classes, but see the sights when he is done in the evenings.  Thanks in advance for all the great advice!
