My saga (and anxiety!) keeps growing

...
Tuesday, our 7-month window opens...and I have NO ideas! Well, OK, I have a LOT of ideas, but all of them involve a lot of stress and anxiety.
Our dates: Oct 15-22
As of today, the 15th, 20th and 21st are unavailable at BWV. I see the chances of getting 4-5 nights in a row dwindling...
Yesterday, I was stunned to see THE ENTIRE WEEK available in a 1BR value at AKV...my home resort. So it got me thinking...
Since we love to eat at Boma on our departure day, what if we try to START at BWV instead of END there? Hmm...that won't work right now because that first night is not available. Then, I remembered that the rest of the family does not want to go to a park on our (their) arrival day so we are planning to eat dinner at Disney Springs on Saturday. We've never stayed at Saratoga Springs

....so I'm thinking about booking a studio for the 15th at SSR. Then, if I'm lucky, we can move to BWV for the next 4 nights and finish the trip in a 1BR value at AKV for the last 2 nights. This will make it super easy to eat at Boma for breakfast on the day we leave

. I would waitlist for the arrival night at the BWV, just in case it comes available so that we would only have to move one time. This is probably the "best" plan in regards to maximizing our time with the rest of the family, but it comes with the cost of moving twice and stressing about a waitlist.
I also have another, probably more doable scenario....
I have another reservation right now for our first two nights in a standard studio at AKV-J. If I keep that reservation, and if there is availability, we can do a 1BR LV at BLT for the last 5 nights. This isn't really ideal since it would mean that we would not be staying with the rest of the family at all, but it would probably be the easiest reservation for us to get at this point. We have no problems with OKW or AKV, but we've stayed at both of them, more than once, and this will probably be our last family trip to WDW for a while. I'd really like to try something new and BLT is one we have not tried as a family.
To add to my anxiety, I still haven't decided if we will be flying out on Saturday afternoon (from Flint with the rest of the family) or surprising the kids by flying out of Grand Rapids on Friday night. It will cost about $350 more to fly out on Friday and stay at the airport Hyatt that night (which is the ONLY hotel option I will consider), but we could take DME the next day and spend some time in a park before meeting the rest of the group at Disney Springs for dinner. I've actually booked DH, DD13 and DD11 on the flight from FNT using points, so *I* don't even have a flight to MCO yet!
The rest of my family is starting to stress about ADR's

...good grief! We don't even have a place to stay!

...heck, I don't even have a ticket to get there yet.
