(Note this place also offers ‘real food’)
Me either and the room could be unbearable at times. That’s why making up snow days sucked so much worse. We knew it would be sweltering for that extra week. We didn’t have fans even. Every kid was melted into the chair and fanning themselves with their notebook. For the younger people notebook denotes sheets of paper bound together that you wrote on, not an electronic device. 
Or the variation: Free Local Calls, especially in this age of cell phones. Remember when all hotel phone calls went through an operator? And they’d charge you out the wazoo for them.
It may have been worse with fans. We’d have these ginormous things sitting in the back of the room droning on and on. It made me very sleepy.
There was a Chinese restaurant about a mile from where I used to live in Cleveland that displayed a large neon “AIR CONDITIONED” sign on the facade.

“American owned” is code for “not a Patel motel”; basically, not owned by Indian immigrants. It was far more common in the days when Indian immigrants first got involved in the motel business. Often the motels they owned weren’t operated in the most professional manner; e.g. owners cooking curry behind the desk, rooms not cleaned properly, etc. Today, Indian-American owned motels are run in a far more professional manner, but the reputation persists. Yeah, the code is racist in a way. I see fewer “American owned” signs now than in the past.

Hanging below the main sign on hinges so it swang in the wind.
When I was a teen I would imagine adding an extra “O” to certain motel reader boards so it said “Free HOBO.” I still giggle when I see HBO on motel signs.
AAA approved!
A sign I remember seeing “Recommended by Duncan Hines”.
Haven’t seen one in years.
Presumably, D-H was some kind of rating agency-does anybody know if it still exists?

Luxury.
Last fall we went to Disney World and stayed at the Pop Century Resort. Along the entrance road to the hotel you can see signs promising Color TV, Air Conditioned Rooms, and the ever popular Heated Pool!
This particular hotel was opened in 2003, so the signs are just a bit of whimsical nostalgia.
Duncan Hines was a person! He was a traveling salesman who kept lists of the good and bad places he’d eaten at while on the road, and eventually started giving them out to friends. In the '50s he had them published. He was kind of a precursor of Roadfood.
P.S. No, it doesn’t exist. But I have another book from the '50s at home that is similar; I don’t remember the name but it was sponsored by a car manufacturer. I’ll look.
My mom and I go antique shopping, usually in the summer. Some of those little stores are in buildings from the 50s and 60s and have no AC. And as bad as it’ll be outside (in California, in July or whatever), it’s even worse inside. But we still go in. 
Motels with cool neon signs are gradually going extinct (I’m talking the older, blue highway-kind of places). Some places that still have them don’t turn them on…trying to save on their electric bills, I guess.
Until recently, the local Best Inn prominently advertised “Free Special K Breakfast” on its sign.
I’m more confused and amused by the catchphrase “A House by the Side of the Road”. Is it advertising convenient access from the road, or what?
And what are Sample Rooms?
That’s a good bit of nostalgia. I do remember sitting in elementary or middle school classrooms with the windows open, lights off, and fans blowing. Made you very sleepy.
This “EAT” was on every night for 50 years and was turned off for good seven years ago today.
Do they still have the signs on the Interstates, every ten feet which say, “Visit Rock City,” and “See Ruby Falls”?
Obligatory Frasier reference.
