We have booked the Chacchoben ruins tour (the shorter one) with David and Ivan. I just confirmed today. Our DD and DS are 4 so we can't do it through DCL. Some people say young kids like it others say it's too much. We know alot will be over their heads, but it's a once in a lifetime opportunity for us. Now we just need to work out Cozumel and decide on a Palo night and brunch day. We will probably just hang out on CC.
