The Lorraines (except for Skits) are out on a walk, and Helen and Martha are hungry, so Danny decides to stop at a pizzeria. The humans enter, but Martha isn't allowed to since the restaurant doesn't allow dogs. Later, the Lorraines are about to go to a science museum, and Martha wants to come too but the museum doesn't allow dogs either.
This makes Martha sulky, so Skits tries to cheer her up with a dinosaur toy. It doesn't work, so Martha goes and sits at the table, then a trivia quiz show comes on the radio. She knows the answer to the question, so she calls in and answers correctly (it's the name of an island that shares its name with two First Ladies, and it's also her name). The prize is a trip to a bed-and-breakfast called the Come On Inn, but unfortunately it doesn't allow pets.
The Lorraines refuse to go to the inn without Martha since she was the one who won the trip, but don't know how to deal with the problem. Luckily, she spots a photo of Grandma Lucille, which gives her the idea to go to the hotel disguised as Helen and Jake's grandmother. Danny accepts the plan, but wonders how they will deal with Skits. Martha replies that Skits can stay behind since he loves being babysat by Carolina, so they head off to the bed-and-breakfast.
They meet Beverly the owner, and despite Martha catching a frisbee, Beverly is fooled. Then, the Lorraines go swimming in the pool and Martha wants to also, but she can't swim in her disguise. She meets an old ex-sailor who calls himself Boomer, and tries to shake hands/paws with him, but Helen quickly splashes her with water and then takes her inside "to dry off".
That evening, Boomer has dinner with the Lorraines and reveals that his glasses were eaten by a fish, but he wants to get them back rather than buy new ones. He says that there is something "different" about Martha, but luckily doesn't know what it is. Then, when he calls her "special", she returns the compliment, to which he replies that he's "just an old salty dog". Martha takes it literally and asks what breed he is and if he's in disguise, then she barks at a squirrel. Danny covers it up by pretending he was barking as an odd way of showing appreciation for the meatballs.
After dinner, the Lorraines go on a hayride, but can't take Martha since there's no way she can go in her granny disguise. As she sulks about being left behind, she smells food on a bellboy's tray and tries to follow. A housekeeper sees her, so Martha quickly ducks into her room, then plays dumb when the woman knocks on the door and asks if she's seen a dog.
When the woman leaves, Martha, bored, decides to call Skits, but then she sees the room service button and decides to order a bunch of meat instead. She eats it, then takes a nap, but when the housekeeper sees her surrounded by bones and clothes, she thinks she ate the granny. This causes a commotion, during which the fire brigade and a news crew show up. She eventually ends up in the lobby, where she makes an irate speech about the hotel's no-pet policy. This causes the guests, who all happen to have pets, to leave so they can play with them, and even the housekeeper leaves due to missing her cat.
The Lorraines come back from the hayride and apologise, but Beverly tells them not to be sorry and changes the rules so that pets are now allowed in the inn. At dinner, Boomer (who has brought his parrot Ishmael) finds his glasses in the fish.
