Crowds and long lines of shoppers are by far what people dread most about this time of year. But more surprisingly, 35 million Americans actually despise "having to be nice" during the holidays, according to our recent poll.

Our survey, asked people what (if anything) they dread most about the holidays. A whopping 90 percent noted there's at least one thing that they stress over during the year-end festivities. Along with the chief complaint of holiday crowds, "gaining weight" and "getting into debt" both tied for second-place in top holiday woes among survey respondents.

"For all the chatter about nostalgia, family fun and gift giving this time of year, many people don't like too much of a good thing," said Tod Marks, senior editor at Consumer Reports.

"For many folks, the holidays are a lot like the Super Bowl. Even if you're not a football fan you watch the game because it's a big event," Marks said. "With the holidays, you may not like the game, but it's part and parcel of the season. It's just what we all do."
