New research from the business advisory firm found that predictions of strong economic recovery in the region are boosting the performance of the hospitality industry.
Phuket, Thailand, has reported the largest increase in RevPAR for the four months ending 30 April - up 31.7 per cent on the same period last year, with occupancy levels increasing by more than 30 per cent.
The Australian, Chinese and Hong Kong markets also performed well in the first four months of 2010, with the region showing signs of growth in international tourist arrivals and passenger traffic.
Alex Kyriakidis, global managing partner of tourism, hospitality and leisure at Deloitte, said: "With an outlook of strong economic recovery for Asia Pacific, hotel performance has benefited and RevPAR is only US$14 (£9.73, €11.35) short of levels achieved pre-recession.
"The region is also leading growth in international tourist arrivals and passenger traffic, so if this trend continues, RevPAR may push past the US$100 (£69.47, €81.06) at some point this year.
