When Ted leaves the room with the married couple, his hair is visibly shorter than when he was in the room.

The position of the injection piston in "The Misbehavers" changes its position when the girl pulls it out of the picture

In "The Wrong Man", Sigfried's bow tie changes from a clip-on to a real bow tie.

In the segment "The Misbehaviors" when Antonio Banderas's character looks out of the bathroom towards his children with his cigarette, it is noticeably longer than it was just frames before.

In the segment "The Misbehavers" the girl calls room 409 to check if they have needles as well but it's actually room 404 (from the previous segment "The Wrong Man"). Earlier the real Theodore just mentions room 409 when his friend at the party calls Ted for ice and he can't remember which room they are in.

Madonna's character Elspeth plays a Coven witch. She is wearing a cross in her scenes which is an error as witches don't believe in wearing crosses, They mostly wear a pentagrams.

In the segment The Misbehavers, a bottle of champagne is spilled, then catches fire. The alcohol content in champagne is too low to ignite.

When Sarah is on the phone to Ted discussing needles during the misbehavers segment the camera wobbles when Juancho is shaking the bottle of champagne (at around 55 minutes).

When Ted is talking on the telephone to Margaret, someone is clearly seen walking behind Ted. This couldn't be another bellhop or hotel staff, as Ted is the only person working that night.

When Betty is talking to Ted on the phone, you can see the camera as she turns around and starts walking to the left again.

After the Jerry Lewis speech, the cameraman's shadow is visible on the back wall.

The hotel's vintage telephone switchboard adds an element of comic chaos, but it is not consistently used. Ted answers calls to the front desk by pushing cables into jacks, but Sarah (the little girl in "The Misbehavers") is able to dial another room directly. Also, when the partying guys call and don't know what room they are in, Ted should be able to get the room number right off the switchboard which means that Ted had no excuse to deliver the ice to the wrong room. Also near the end of the scene, Ted is shouting into the phone to send the police but this would be impossible because there was no-one on the switchboard to connect him to an external line.
