For a trip coming up in two days, I just got an upgrade confirmation email. Great! The problem is, the room I originally booked had a large balcony (lounge chairs, etc), and the one I got "upgraded" to, is a smaller balcony (standing room only), but on a higher floor. Since this is a resort property, the higher floor is a "Deluxe Oceanview room," while the original booking is just "Oceanview." Besides the size of the balcony, the rooms are identical.

I specifically booked the larger balcony room, since my wife and I are traveling with two little kids, so we'd like a place to hang out while they are napping in the afternoons. The balcony would be perfect for that, and the upgraded room does not have a large enough balcony for it.

I am on the phone with Hilton now, but I am being told the "deluxe" room is an upgrade, although everything about the room on the hotel website shows it as the exact same room, but on a higher floor. I would much rather be on a lower floor with a usable balcony, than a higher floor with an unusable one.

This is a points booking, if that matters. Re-booking today to get the room I want would be significantly more, as there is no standard room availability left.

Has anyone declined an upgrade before? I'll report back on how the call goes, but I am curious if anyone else has experience with a similar situation.

It's not relevant, but this is at the Hilton Cancun Mar Caribe, a recent Hilton addition.
