The ambiguity over what constitutes "public entertainment" has left the operators of Bangkok's nightlife somewhat in the dark.
Similar ambiguities a year ago, when the late king died, led to some venues being told by local police to stop selling alcohol or close early while others continued their businesses as usual.
Thais have resumed wearing black this month, after life returned to normal since the monarch's death last year. Many social media users have changed their profile pictures to black and white again.
Most television channels and websites have gone monochrome, with entertainment programs to be replaced by documentaries on Bhumibol's life and work from October 13 onwards.
Tourists are asked to be "respectful" to Thai people's feelings as they bid a final farewell to the king.
All tourist attractions remain open as usual except for the Grand Palace and the adjacent Temple of the Emerald Buddha, which will remain closed until October 29.
Bhumibol, the world's longest-reigning monarch, died last October at age 88 after seven decades on the throne. He was deeply revered as a moral authority and a unifying father figure amid Thailand's numerous coups and political conflicts.
His cremation will take place at a public square in Bangkok, where an enormous wooden funeral pyre is being erected.
Thai Buddhists often wait a week or more before cremating their dead but royal funerals are exceptional.
