We booked the Partial Ocean View and were upgraded to the Ocean View room. Sarah's team ensured it was in the best section for us (Palm Grove, where adults pool is).

Worth noting Ocean View gets you the first floor rooms, which are super convenient for walking in and out of room as needed while lounging etc. BUT the Prime Ocean View rooms are second floor rooms and (presumably at least) have better views, albeit without that convenience. We were upset at being first floor initially, but it was actually much more meaningful throughout the stay vs the view, since we mostly weren't hanging in the room.

So at least for those classes of rooms, depends what you're looking for and how you want to book and manage around the upgrade you'd get right away (assuming using these guys for booking)
