From what I've seen, most places "actively" promoting tourism (which is going much too far - I haven't seen any advertising for travel or vacations in the last 2 months) are realising that 2020 will be the year of the "staycation"; I really think that anyone who sees a plane journey as a necessary part of their summer holiday 2020 will be severely disappointed, or may have to factor in a period of self-isolation either at their destination, upon their return, or both.
