Mrs Suphajee says the firm needs to preserve cash flow until the end of next year.

Dusit Thani has developed back-up plans to cope with uncertainty related to the pandemic and slowed new hotel investments to preserve cash flow.

"Given the ever-changing situation, we have to preserve sufficient cash flow until the end of next year," said Suphajee Suthumpun, group chief executive of Dusit International.

Dusit Thani has cash on hand of 1.26 billion baht and unused credit facilities of about 1.25 billion.

Plans to expand villas under the Elite Havens brand in Australia and Europe were already put off, as well as a project to buy new hotel properties in the UK and Japan.

The company will continue its mixed-use project, Dusit Central Park, which should be completed when the market returns to normal, focusing on the food business in the interim, she said.

The company prepared a financial model based on three scenarios. The best case scenario is tourists being allowed entry to Thailand by the end of this year in limited quantities, ideally long-stay tourists.

Mrs Suphajee estimated the most likely scenario is leisure tourists will start to pick up in the middle of next year.

Dusit Thani has to streamline work flow in the organisation, such as by grouping marketing and sales departments into regional clusters or consolidating the headquarters, instead of letting each hotel work separately, working to build a technological transformation, she said.
