We did this last year on the 4 land/3sea trip. We stayed at POR and they picked up at 12:15. I don't think they pick up much earlier than 11:30at the other hotels. We also stopped at one other hotel. I believe we got to the port around 1:30. The one nice thing about the package was that we did not have to check in at port, we walked straight in. If you want to go earlier, you'll have to arrange transportation outside of Disney, such as a car service or renting your own.
