To clarify a bit, this is in essence a room downgrade, because the total square footage of the room is smaller by about 120 sq ft, after factoring in the balcony. However, since it's on a higher floor, the hotel considers it an upgrade. We really need that balcony for a place to hang out, otherwise, we'll be sitting in the dark in silence every afternoon from 1-3pm while the kids are napping. Sounds trivial, but it's significant, and why I booked the original room type I did.

Original booking: Ocean View 2 Queen Beds - Large Balcony
"Upgraded" booking: Deluxe Ocean View 2 Queen Beds- Juliet Balcony

I finished up my call, and the CSR was not able to get the hotel in house reservations office on the phone to try to get it squared away. She said she put a note on my reservation to switch me to a room with the large balcony as originally booked, but as this is a new Hilton member, and all-inclusive resorts are notorious for not being the best about room things, I'm nervous about it. She said to call back tomorrow to try to confirm, or to confirm with the hotel when I arrive, but that isn't really the path I'd like to go down. Further, today is the cancellation deadline, so I'd like to get this firmly squared away today, or switch to a different hotel in the area, if needed.
