I thought it would be a good idea for a thread concerning the upcoming ceremony and related activities. For anyone with Thai travel during this period, it will certainly have some impact.

The Funeral will take place over a 5 day period (Oct. 25-29). It will take place at Sanam Luang, which is in front of the Grand Palace.
The cremation day will be Oct. 26, which has been announced as a public holiday.

It is expected that throngs of Thais will be making their way to Bangkok to participate in the proceedings and pay respect to their revered monarch. My guess is Bangkok will be at a standstill, especially on the 26th.

I am sure additional info will be available as we get closer to the ceremony.
It has also been announced that the funeral site will be open during the month of November for the public to visit.
