Will you have Standard view or Preferred view? That affects the requests you could make, e.g. some Standard view villas have excellent views of Epcot fireworks.
Are you staying on points (DVC owner yourself or renting)? If so, requests need to be submitted to MS by the DVC owner, via chat or email via the member website or via phone. If staying on a cash reservation made through Disney, you need to call the reservations line to have the request added to your reservation record. You might be able to make a request via chat; I’m not sure.
We are not staying on points we are booked for a 1 bedroom standard view
