It is a lot of fun, but for three full days (5 if you're in a tourist area) it can become tiresome. Because this is a local community, I know how hard many of these families work, and how hard they struggle each day to simply make-ends-meet, so it's nice to see them bury their worries for a few days and enjoy life to the full. If you get the chance to visit during Songkran, 13-15 April every year, then it is well worth it.
