Connecting reservations + Dining Plan

[Moonies]

Okay, so I apologize if this has been asked before (or a lot) I did a search and couldn't find anything.
So here's the scenario:

We're heading to WDW Oct 31- Nov 6 and staying at Port Orleans - Riverside for the whole trip. Their are 6 of us going.

Moonie #1 - Chloe
Moonie #2 - Chibi (dat's me!)
Moonie #4 - Megpie
Moonie #5 - Alex

will all be staying in one room for the full time. We already have booked a Magic My Way package and have DDP for the entire time.

Moonie #3 - Tux
Moonie #6 - Claudia (#1+5's mum)

will be staying in another room at Port Orleans from the 31st - 2nd. They also have a Magic My Way package and DDP for those two days. Moonie #3 is going for a short time because of $$$ yet he's only bought a 1 way ticket for flight so far because he wants to leave it with an open ending as long as he can in case he can afford to add a few more days to his trip. That being said...Moonie #3 and #6 (work and adult responsibilities and all that jazz) will no longer have a room after the 2nd. If Moonie #3 were to be added to our room, and purchase more tickets would he be able to also pay to add DDP for the extra days he'll be staying??? Oh, and both room reservations are already 'connected' if that helps any.

Cheers!!
Moonie #2

Moonie #3 can be added to your room as long as you're in the Alligator Bayou section (although keep in mind that the fifth sleeping place is a Murphy bed that's a bit smaller than a twin), but would not be able to get the dining plan.
