Cloud got very concerned the second she suspected we may be leaving and she would be stuck with just the boys for a week.
Once they spot the suitcase, they know something is up.
They try to find ways to sneak along in our luggage. Or our shoes!
But in the end I think they would greatly regret sneaking along in our luggage and getting stuck in a car for four hours, and then having to stay inside a tiny hotel room. I do get the urge to take them with me though, it would be silly to see how they react to a strange new environment!
