Mother’s Day brunch?

Just booked my dining for May 2020 and got everything I’d hoped for except Mother’s Day brunch at California Grill. I called to book something else (Captain Hook for kiddos) and asked about Mother’s Day special events. The CM didn’t know much but thought maybe there would be some special events that day, and possibly even one at Cali Grill, and that these events are just not released/ available yet. Again, she wasn’t really sure. What do you all know about this? Do they have events on Mother’s Day? If so, they release the availability later?

It’s frustrating when they don’t have all the ADRs lined up when it’s your ADR day. I’ve run into that with Thanksgiving meals.
