Congrats!!
You do know that with your 6 day ticket plus water park option that you have enough to cover your entire stay for entry into to be split between 6 park days and 3 'other' (water park, minigolf, Disney Quest) entries?
And apologies if you already know this....but.....
I will say that this is based on the assumptions that:
1. When you link your accommodation and tickets to your
MDE that the system recognises your stay for 27 Oct - 4 November.
2. You will be able to use your Magic Bands for park entry from the 27th Oct.
So, if you claim you first day in a park on the 27th October, you should have 14 days to use up all your ticket benefits.
Your ticket will only let you enter either MK, Ep, AK or DHS on 6 days. But your ticket will let you enter the water parks, mini golf and Disney Quest for 6
times. These can be on the same day as a park day; or they can be done on separate days to park days. You can also stack your entries into the WPF&M locations on the same day; providing you don't exceed 6
times.
You could decide to do a mini golf experience on the morning of your
MNSSHP and then head to MK on that day.
You could also hit the water parks on 2 of your non-park days to cover your time at WDW.
So, you may be able to play around with the various combinations of days starting from the 27th and build in the days for you to enjoy the WPF&M options of your ticket; without having to wait for the 29th to come round.
I would probably head to the Theme Parks Attraction and Strategies park of the boards to ask the question about whether you can start your ticket earlier/from the day you arrive.
One other thing. I was rather nervous about my MNSSHP ticket being stacked on my MDE with my park tickets last year. In my case, the CM at the resorts cannot see tickets stacked in this way; so if you ask them to check your ticket status, they may not see the MNSSHP listed on their system. The CM at the PARK can see the ticket stacked. I asked how this could be the case.....seems like Disney has two separate systems for the new MDE. One for the parks; and one for the resorts. Go figure!
Congrats again.
