Unemployed people typically don't take vacations. People that are nervous about their financial future also don't take vacations. The people that do are going to take less extravagant ones. I have a lot of friends in the travel industry, and no one there expects travel to return to what is was a few months ago for many years.
Tourism industry is sized for population that does take vacations, and they were denied it this year. And out of 10 million on unemployment, how many you think were taking regular vacations in the first place? The poorest were hit the hardest.
