Which ruins did you visit? I was on a travel forum once and someone called (intentionally) the Chichen Itza ruins the Chicken Pizza ruins b/c it sounds so similar. If you went to Chichen Itza, I might call it, "Chicken Pizza and Other Mayan Memories."
It's Tulum. I've been there too and loved it. How about Castillo Por El Mar. That's Spanish for Castle by the Sea. El Castillo (the biggest ruin there) is just magnificent! Doing the title in Spanish seems fitting.
