Hey folks! I am staying at the Dolphin Oct 26-30...and it can't get here soon enough! I have one question for you experts

Oh wait...2 questions!!!
(1) we arrive early, flight lands around 9:15am. Then towncar to the hotel. I was thinking lunch at the hotel and then either wait around by the pool till check in then head to MK or should we walk right on over to Epcot and just head back around 3 to check in? Will they text me if the room is ready early? What would you do if you arrived so early?
(2) We have a late flight, 8:30pm. Has anyone done the late check out? What do I need to do for that?!
