It looks like Orlando's tourism industry is going to take a major blow following the terror attack at Pulse nightclub this past weekend, which left 50 people dead and 53 people injured, in what many people are calling the bloodiest mass murder in the history of the United States.

New reports say that tourism-related spending is expected to take a nosedive as both residents and visitors will be a little more cautious in the coming months. The Central Florida region is home to some of the world's top theme parks, including Walt Disney World, Universal Studios and Sea World.

According to the Orlando Business Journal, one report says the businesses such as restaurants, investment banking along with securities and wealth management firms will see a decline in business.

New York-based Maxim Group says in their report, "We are concerned that overseas agencies may issue travel advisories for travel to Florida, and that foreign travelers may take their vacations and business travel elsewhere. Although we do not expect travel advisories to be posted for domestic travel, we anticipate that some U.S.-based travelers may exercise caution about traveling in Florida."

After the Paris terror attack that took place in November of last year, vacation-related bookings dropped down by 13 percent as the market is still recovering in that region.

Gunman Omar Mateen attacked Pulse nightclub in downtown Orlando on Saturday night before he was ultimately killed by local police officers in a shootout.
