After Thailand's King Bhumibol Adulyadej died at age 88 on Thursday, the government declared a full year of mourning.
That could affect your travel plans in the country, especially if your visit coincides with the first 30 days of the mourning period, when residents have been asked to wear black and avoid "festivities." Consequently, some entertainment venues, restaurants, and bars may be closed or operating under limited hours (public services, transit, banks, and hospitals will continue normal operations).
The Tourism Authority of Thailand encourages travelers to visit the country despite the somber mood, but recommends taking measures such as wearing muted clothing (though that's not mandatory).
Most tourist attractions will be open as usual, except for the Wat Phra Kaew and Grand Palace in Bangkok, because they're being used for the king's funeral rites.
Australia's Department of Foreign Affairs and Trade has advised travelers to "refrain from any behavior that may be interpreted as festive."
