The royal wedding threads there were 3. The first one in 2011 (but this was before you could add photos, so the photos were on my profile, but now seem to have disappeared.
The other 2 were in 2018. Not sure whether they are still in Chat or Classics (some got moved) but if you search for "Playmobil in our house" on advanced search you will find most of my Playmo threads I think.
The 2012 PlaymOlympics you won't find though, as this wasn't a thread, but MN asked me to do some photos and I think had some kind of page they were on at the time. But I think I did a 2014 Winter Olympics on a thread.
Have also done a couple of advent calendars, last year's summer holidays and a couple of short items (harvest festival/Valentine's day). Oh, and some elections, although I think the Plexit referendum got lost as it was in Chat when that was only 90 days. Hope you find them!
