Good Places To Photograph Loy Krathong?

[Blago1]

I'm going to be in Bangkok at the time of this year's Loy Krathong Festival. I'm an amateur photographer and would like to take some photos of what looks like a very photogenic event. I've heard some of the major areas get very crowded and I'd like to be somewhere where I'd have enough space to set up a small tripod, since light levels will be low in the evening.

Any have any suggestions? How to get to a suggested location by public transport would also be helpful.

Thanks for any input.
