The is trans available but remember you can't get get a bus from hotel to hotel. You would need to go to a park first which would/could take a lot of time. Lyft is probably your best option, unless you have a lot if time to wait/transfer.
We had to use a Lyft that early in the morning.
There are many options for transport. They now have the Minnie lift provided by Lyft. Otherwise I'd check the transport schedules as you get closer to your trip.
