I've never had a Royal but I've had two straight flushes both on Pokerroomin sng's.

The first one, I was playing 8c-9c. Flop came down 10c, 7c, Ad. Two people both made mediocre bets. I called. Jc came down. Massive raises. River was the 6c... (Overkill if you ask me) :-) So now I've hit the 6-J Royal. First guy goes nuts betting. He had AcJs, hitting his two pair and his Ace High Flush. Second guy moves all in. He had A7os. I move all in. All three call. I was on the short stack so I triple up.

Second one, was similar but I hit to the King. I had Kh9h. Flop came QH 10h 3s. Check. Turn was a rag. Check. River came Jh. Other guy had pocket 8's, was on a short stack and was afraid I was slow playing him with overcards.
