Yeah, it’s always better to lead with the “How much would it be to upgrade to [insert desired room here] if there are any available?” - sometimes (read: usually) it’s the calculator and amount and sometimes (read: usually much less often than reading this and other forums would suggest) it’s a “Let me check on that” and pixie dust happens.
I actually had to lead with “Can I be downgraded into the category I selected?” when they “upgraded” me to a Pirate Room at CBR for the weekend I was doing the Goofy Challenge. I have no issues with the rooms as a rule and for a regular visit would have taken it - but a weekend where I was doing 39.3 miles of run/walking and getting up to be on busses at 3am 2 mornings in a row, I did not need all the extra leg bumping things like those ship bed frames. I ended up in a King room, which was an upgrade from my booked standard room. LOL. I think I had added in “I’d just rather that pixie dust go to a family with a child who would love it!” which made the CM smile.
