Flight time from Hawaii appx 12 hours but kids said its worth it to go to WDW.
This past holiday we went to Disneyland since that is only a 5 hour flight away but after about 1/2 a day they said "Is that it?!"
So next time its back to the 12 hour flight.

::cop: My one and only so far too since I've been driving! So with that don't know if we saved much over flying.
It took us around 24 hrs... not exactly sure but very close to around that amount of time. On our way back home we took it much more leisurely. Stopped at the Over the Boarder (? did I get the name right?) place at the Border to NC & SC. And spent a night in Washington DC to see the sights there too. We were going to stop for the night at NYC too but from what we saw it was sooooo much $$$$$ just to park and we were a little travel tired so decided to continue on home.
For me it's much easier as I don't enjoy extended periods of time in a car. And our small local airport is 5 minutes away from me so easy commute and getting checked in there! The flight is about 2 1/2 hours which for me is so short since I am used to the longer flights to CA and Europe from here. I like taking the earliest morning flights out there and the latest evening flights back to home. Gives more time to be at the parks/resort. And the first day we come in we usually rent a car (at the alamo or national in disney) for a couple days to go shopping for groceries & at the Outlet stores for all the disney stuff! Also do the other parks such as Sea World, Universal and Busch Gardens those days too. 
, 2 hours (give or take a few minutes to fly) and lately we've been lucky with ME so within an hour....WELCOME HOME!! All in all, it's roughly 5 hours from the time we leave to the house until we 2 of the best words in the language...Welcome Home!! (which means it's about 6 hours from the time we leave home that we wind up at MK!)
so we pay the airfare.
