actually b4 that (since months ago), already have reports suggesting tourists dont visit BKK during Oct periods. anyhow since you already bought the tickets, go there and see lo. no choice right? Just be prepared to get very packed and maybe a lot of big malls also have their own "pay respect" event...security gonna be tight, so try bring as little belongings e.g small pouch, if need to.
is gonna be a big big event.
I think most of the media (TV channels) will go into monochrome tone (black and white) soon.
