Hello! First-timer needs help. This will be first time trip for us. Party of three- myself, DH, DS (6). I'm nervous because it is our first-time trip to Disney, and we are going during Christmas Week -20-29th! EEK

We are sort of "forced" as well because of our jobs, but we really are excited to see Disney at Christmas! I could use help from
anyone that has traveled on Christmas week. That week seems different than any other week in December. I researched a lot before my ADR's, but like anything, unless you have experienced first hand, you have no clue. This is our schedule (I hope I'm using the correct initials to communicate all of this
I put my questions in bold.
20 - can check in early; EP- tour Future World-tried to get ADR Garden Grill but no luck
When would be best to retry for GG this day?
21 -EMH@MK- tour Tomorrow/Fantasyland early ADR lunch
@Crystal P- leave park by noon; nap @ hotel 3/4 hours; PH to HS; use FP+ afternoon; late dinner @ 50's ADR- stay until close-see Osbourne lights.
Will buses from Caribbean Beach resort get us there for EMH this day? I'm assuming that is going to be REALLY early
Should we drive that day (have car)??
22– RD MK tour Adventure Land/Liberty Square; early lunch QS; hotel rest again; MK, FP+ afternoon; dinner late QS; fireworks/parade- stay until close-
What is the best way to see parades and fireworks this day at MK? I don't get the parade situation this day/week. It says there is 3:00 one, is that the same as the night one?
23- RD HS Jedi sign up, see shows (most rides@ HS will be afternoon Fastpassed); lunch QS; break; HS; FP+ afternoon; ADR Sci-Fi-latest show Fantasmic!
24- Rest in AM; lunch @ hotel or Epcot QS; afternoon FP+ ride not seen, evening at Epcot World Showcase; ADR Biergarten; Illuminations- thought about CP, but we might skip it this time- son is high energy and read it could be boring for young ones
25 – AK (
may or may not RD Christmas morning??? any thoughts on this?- I've heard it is not crowded); latest brunch @ Tusker House; FP+,
Is there an AK Christmas parade we can catch in afternoon this day??? Leave AK early afternoon; X-mas Dinner at 'Ohana.
26– (no park day) Hotel Rest AM -Christmas resort decoration self-tour.
What are the three best resorts on monorail to see???- DS will probably be interested in doing this for a little while- can't see all of them; ADR dinner California Grill.
27– RD MK; BOG lunch (the only time I could get BOG!!!)-
not sure when to FP this day and not let it get in the way of our ADR @ 11am. Should we do before or after 11:00 ADR???. Break; Downtown Disney Ragland Road ADR
28 (no park day) Rest in AM; ADR Chef Mickey brunch; break; PM: Downtown Disney- ADR T-Rex
