Phil (Ty Burrell) closes the last room of a nearby hotel with only one single full-sized bed.
Phil feels betrayed, but Haley (Sarah Hyland) wonders why some of them can not stay with Claire so everyone will be more comfortable.
Phil, inordinately hurt by the kids and Claire's behavior, ends up trying to teach the Nigerian family located next door with noisy dogs how to play Marco Polo and fails miserably.
Haley and Alex (Ariel Winter) find out that the hotel was half-full the whole week and they realize that Phil lied to them so they could all spend time together.
Mitchell (Jesse Tyler Ferguson) gets a bit tired of it and tries to stop Cameron of following those superstitions but with no luck.
