Swan/Dolphin no longer have Disney owned busses and use Mears busses. The only big difference is at MK it drops you off at TTC instead of the inside bus loop. You can always walk over to BW or YC/BC and take their busses, but a lot have reported by the time you walk over there you aren't really saving any time.
You get both Early Entry and Extended hours staying there, just have to link it to your MDE account.
