Good question Katie. I will be at the Sheraton but do I have to get to McCormick place and register before the tour. Does the tour leave just from McCormick Place? How early are we going to be gettin up??? I hope the poor souls in my room will have that tour also. Yes this all makes me a bit anxious. Ann--Who knows everyting--do you know these things and do you know how far apart the Hilton and the Sheraton are? I hope there is a Starbucks and a drug store near the Sheraton. Anyone know??
