I recently booked 1 night with HW pre cruise for PORR-Mansions (royal term was dead give away

). Booked for only 2 PP the end of March. Wound up less than value i had booked, $173 all in, i was happy
Did contact HW to verify that we’d receive the Mansions. Took a good half hour on hold, but she verified with WDW we’d be in one of the two standard buildings but with a garden view.
While we were chatting, I inquired as to the problem I read here as to adding children on after the fact; whether calling WDW or requesting the booking agency make the change.
She said they ran into issues when people would book for 2 adults & then request to add children. Often, it would turn out the children were over 10 y.o., identifiable by their
MDE accounts. WDW was likely not happy to be lose the extra adult room fees.
Wonder if the extra rates for kids that’s being imposed is a Disney mandated price increase of some sort. Due to those who had caused red flags to fly. Certainly would penalize those who legitimately are just attempting to add their under 10 y.o kids to a HW res
