The resort scene has Dave and Gwen roasting marshmallows. There's three stone benches around a firepit. Two benches had pads, the third one did not. An older couple sits down next to Dave and Gwen. They roast marshmallows and talk. Gwen leaves to join Alex in the hotel lobby. The camera pulls back and shows Dave sitting alone with two empty benches. The older couple was gone from the scene. A few minutes later, it again shows the same scene of Dave sitting alone. The same empty benches, one with a pad, and one without were visible. Gwen returns outdoors to the firepit looking for Dave. Dave is gone, and the older couple is sitting there. It's made to look like the couple never left, yet they were missing from the previous scenes with Dave.
When making fun of "the carnations like a horse at the Preakness"; those champions receive "Black-eyed Susans" from the state of Maryland.
The .mov file that emails to Alex is shown as being only 326k (kilobytes) is size. That would make for an extremely short movie (only a second or two).
Front seat head rests are missing from Gwen's van.
