The only way it can be done is to change resort or room type / view. So if you went from a Studio to a 1 BR or preferred view to standard. Obviuosly, it would also require you to move to another room.
We are doing this on our arrival day. We are staying in a Standard view room at BLT because we arrive at 8pm at night and getting deluxe dining for that one night and moving to a Lake view the next day. Works perfect for us!
