Hi All! Not sure if this is the right forum for this question, but it seemed the best fit 
We've been to WDW many, many times, but this year will be our first time visiting over NYE. We have a room booked at BLT for four nights.
We do not currently have our tickets yet. Our AP's expire mid-Nov and we are not planning to renew, so we'll just be getting day tickets ($$$$)
.
That said, I am debating where we want to spend our time. We have 3 1/2 days in the Orlando area and then 2 1/2 days in Cocoa Beach area.
I'm considering 2 days in the WDW parks... probably MK on 12/30 and EPCOT on 12/31..... but I'm debating just doing MK both days since we can walk to BLT. Any thoughts on one plan over the other? How bad will monorail transportation back to BLT on 12/31 be after fireworks... are the EPCOT fireworks worth the trip over there (in lieu of MK's fireworks, which we'd have already seen on 12/30)? OR, and this is a big OR, I'm considering only buying one day of park tickets (for 12/31 in MK) and just watching the fireworks from BLT on 12/30 (and doing something non-Disney during the day). I am aware MK risks closure on 12/31 so we'd plan accordingly (enter early and stay, make ADR in the park).
For our other full day I am debating Sea World (we'll have a car) or if it's really warm, a day in a WDW water park. I know Sea World is not Disney.... but can anyone speak to crowds there over the holidays?
For our time in Cocoa, fingers crossed weather is decent enough for some relaxing by the pool (heated) or beach for 1 1/2 days. The other full day we hope to go to Kennedy Space Center..... again, anyone know how crowds would be there?
Any other thoughts appreciated!
