Thanks SW and others for your helpful hints.
My first day toward the Queen’s Garb and I have picked 7 giant petals. 4/5, 2/5, and 1/5
So it would appear that for me this goal will take about 5 days.
I am working on the other goals at the same time, and finally have a few energy left to tend to some of the rest of my kingdom.
It looks like S8 have managed to find a way to slow many of us down, so that we end up playing for the full time of the event.
I am so glad some still manage to forge ahead.
