National Aquarium generates more than $300 million for Maryland

Most visitors come from out of state and inject fresh money into local economy

Attendance at the National Aquarium this year is expected to tick up a little more than 1 percent to 1.33 million, but remains significantly below levels experienced several years ago before the recession. Still, an economic impact report to be released Wednesday found that many of the visitors to the Inner Harbor attraction come from out of state, spend a good deal of money in the region and cite the aquarium as the reason they came.
