In Whitstable, a British seaside town just over an hour’s drive from London, every day of the last two weeks has been like a busy summer weekend. Britons may be unable or unwilling to take international flights, but with the first easing of lockdown restrictions, they are more than happy to head to the beach to bask in the sun and eat fish and chips from the only restaurants open for now.

Optimism that people everywhere will be eager to wander once travel restrictions end drove a rebound in airline and tour-operator stocks last week. But these hopes may be overdone. Lingering health concerns and uncertainty about which borders will open mean many consumers on both sides of the Atlantic will stick close to home this summer.

What’s more, they may favor a remote Airbnb rental instead of staying in a hotel, with the increased chances of running into other people in the lobby, elevator or restaurant. Globally, new bookings at Airbnb Inc. and Expedia Group Inc.’s Vrbo more than doubled from 916,000 in the week of April 5 to 2.08 million in the week of May 18, according to AirDNA, a short-term rental data provider.
