Fewer than half of all Americans — 49% — plan on taking a summer vacation this year, according to a new Marist poll. That’s down from 63% when the question was posed two years ago.

More than one-third of Americans — 35% — report they have changed their travel plans to specifically save money. And nearly four in ten Americans — 37% — are planning to spend less money this year compared with their last vacation. Half report they will spend the same while just 13% report they will shell out more.

Marist surveyed 1,128 U.S. residents between March 9th and 11th , 2009 by telephone. Results are statistically significant at plus or minus 3%. There are 533 people who plan on taking a vacation this summer.
