U.S. investors seem to be demonstrating growing confidence in the state of the economy by leaving town.

About 82% of the investors polled said they plan to take a vacation this summer; in 2010, only 73% of the investors took a summer vacation.

About 60% of the participants said they expect to spend at least as much on vacations this year, and 20% said they expect to spend more.

John Hancock, Boston, a unit of Manulife Financial Corp., Toronto (NYSE:MFC), has published those figures in a report on a quarterly investor sentiment survey series it started earlier this year.

For the latest survey, a polling firm surveyed about 1,146 investors online in May. Participants had to participate in household financial decision-making, have an annual household income of at least $75,000 and have at least $100,000 in assets.

Hancock found that survey participants were optimistic about their personal financial situations but concerned about rising gasoline prices, health care costs and the federal budget deficit.
