I imagine cancellations skyrocketed and bookings halted for a few weeks in the spring, but by summer they started to publicly reveal trends were working in their behavior. The number of bookings was a bit depressed, but the number of nights booked had actually increased. In covid times, people seem to prefer staying in a private home for 1-2 weeks over sharing hallways with other guests at hotels for a few nights. With WFH, you can even relocate to an airbnb for a month or more.
