That is not likely. Busses start to run about an hour or a little more before park openings and the earliest opening is right now 9. To get from AKL to OKW you need to take a bus to a park (or Downtown Disney) and then catch another from there to OKW--that trip can often take an hour. Highly recommend you get a cab which are available at all the resorts.
Please Note: Downtown Disney Bus Service won't start running until 9 am, During the Summer when Typhoon Lagoon water park opens at 9 am the Bus will start running at 8 am.
