I believe the Harmonious Dining Packages are prepaid when you make your reservation. Asking for a refund may be treated differently then asking for a waiver of a $10 fee.Maybe that was the regular, ADR policy and not the Special Event Dinner Package policy. Who knows... all I know is when I got to Rose & Crown Fireworks Dining with 2 instead of 3 people, they told me sorry but they would have to charge me for the 3rd person regardless, and they did. They offered to give me the third meal as a to go meal for the room, but we were leaving the next day. Policy or no, I'd also call ahead and fix the reservation.
Different restaurant. I'm sure this doesn't apply to poster I quoted
Spice Rd Harmonious has 4 tables for 4 and 4 tables for 2. Assume a couple added a ghost to their reservation. Either to get a better table or due to availability. No reason to offer a refund
