The bubble definitely includes DH, especially once they get that end of DTD back up and going. PP remains mostly 'outside' the bubble with the need to walk through parking lots -- but the new gate to DCA really improves on the bubble feeling for PP goers.
Early Entry makes a difference for hotel goers rope droppers which most locals don't do unless onsite and most little ones still struggling for breakfast and getting ready. One can plow through fantasyland or hit all the mountains before the masses arrive en force after 930A. It's similar to the post fireworks 1000p-12mn runs that locales love.
