I don't have advice for the twin part but can say even my 2 and 1/2 yr old wakes sometimes early from napping crying. but since I olny have one, I know when she wakes this way she is not yet ready to wake and if left alone will lie back down and go back to sleep. I read they have a 45 min. sleep cycle so they have gone through a cycle but aren't done yet. if you can wait it out. that works for me. jsut so you know, most of the time my husband can't wait it out, but if I'm home, I can tell she isn't done yet.
