The Business Times reported on 17 March 2022 that "recovery in visitor arrivals to Singapore is expected to pick up further over the course of 2022 to benefit hotels in Singapore as usage of the Vaccinated Travel Lane (VTL) scheme continues to grow". New initiatives that will further boost visitor arrivals were also announced by the Singapore Tourism Board (STB) such as the planned expansion of Resorts World Sentosa, recent extension of Singapore's contract to host the Formula One Singapore Grand Prix, and several major MICE (meetings, incentives, conferences and exhibitions) events for 2022.
