We are planing a trip from Naperville to Sacramento on the California Zephyr. We will be in a Roomette. We can't check luggage at Naperville so I'm curious about the Superliner luggage rack. What are the chances there will be room in the rack at Naperville for a larger roller suitcase? Naperville is the first stop west of Chicago and I have heard that the rack is sometimes full. What are the chances that rack will be full and what does one do with their luggage if it is? There will be two of us in the Roomette so I don't see how it would fit in there. Are there other places besides the luggage rack to store luggage? Should I take the luggage to Chicago and check it? Not the most convenient but it beats sitting with a suitcase in my lap for 2 days.
