In some older trip reports I have read that Shades of Green has full sized cribs and not just pack n plays? Can anyone confirm that this is true recently? DS will be 4, but has autism and still sleeps in his crib. I think he needs that containment to lay down and sleep. I was going to try a regular bed with bed rails, but I've been nervous about a long night of him getting up. A pack n play is just too small, he's a pretty tall boy! If we need to we will probably rent a full sized crib, just curious if anyone knew.
