Four in a Bed viewers were left doing a double take during Thursday night's show as guests arrived at host Karl and Steph's B&B in East Yorkshire.
As the Channel 4 guests travelled to Cedarville Guest House in Withernsea, the couple were aiming to make a good first impression with their budget home away from home.
Some guests weren't so pleased, as Sian and Mary felt the view wasn't up to their standards and weren't happy about the space given in their rooms.

But viewers were more distracted by Karl's distinct resemblance to Benidorm star Tony Maudsley, who plays funnyman Kenneth in the hit ITV sitcom.
Taken aback by the shock resemblance, fans flocked to social media to air their funny opinions about the down-to-earth Channel 4 star.
One Twitter user said: "#fourinabed Quality vest today Carl."
Another user simply posted a picture of Kenneth, alongside the caption: "#Withernsea #fourinabed #carl #doppelgaenger #kenneth"
Other fans saw a resemblance to Rab C Nesbitt, with one Twitter user writing: "#fourinabed welcome to the seaside", alongside a photo of the comedic fictional Scotsman.
A fourth comment said: "#FourInABed Carl,if you wear a vest in public don't forget to wear a bra."
More comments read: "#fourinabed as much as I want to not like Carl for his vestiness I do like him", and "#fourinabed Karl's missing something here. A tied hanky on his head! With the added bonus we wouldn't see his haircut."
Payday is tonight for the Four in a Bed stars, and it's going to get spicy as Sian and Mary left a scathing review of Karl and Steph's place.
Tune in for all the drama on Channel 4 at 5pm on Friday, April 1.
