You've got an asset, not a problem. It's really hard for us to travel from the west coast to WDW and deal with the time change that direction. It is so much easier to come to the west coast and get up early. You can easily use early entry, have early breakfasts, swim if it's warm weather, walk through the lobbies of the resorts, shop, etc. And if you are coming in off season, the parks close at 8pm - unlike WDW where they stay open much later at night - so if you take advantage of early entry you will make the best use of your time in the parks.
