BiggusDickus (what a graphic name), I agree with you that Songkran is worth a trip, even from across the globe.
But my experience of one GCircuit party was not worth any trip, except the return trip. At least not being by oneself, as you say most attending are in groups. There is much eye candy (if your eyes don't mind the clothes) but, if none is available, isn't this some sort of masochism? Why not attend a Songkran party at a gay sauna, where the meat market is open?
