Washington, DC (ABC) - The number of travelers is expected to drop 30 percent this year but experts predict an increase in 2021.
The United Nations World Tourism Organization reported a record 1.5 billion global tourists spent at least one night in a hotel or motel in 2019.
This year has been a very different story.
Airlines have grounded nearly two in three plans and cruise ships remain docked.
An estimated 8 million workers have been laid off or furloughed in the tourism industry in the United States.
So where is the optimism coming from?
Hotel chains like Hilton and Marriott, and popular theme parks like Universal Studios.
They've announced major new cleaning procedures worldwide to attract visitors.
Universal said it will practice social distancing on their rides.
Wynn Resorts said it is thinking about sanitizing dice between each user as a way to reassure the public it is safe to travel.
