Side note to your side note: I don't know what the parent was referring to but if I had to guess, I'd guess Goa Parties (which are a thing) as opposed to Parties in Goa.
Goa Parties (in my experience anyway) involve Goa Trance music[0] and are sort of their own subculture but it involves people from all walks, e.g. from Burning Man techie decompressionists to German hippies and beyond. Oh, and drugs, though not mandatory.
But I'm no expert so maybe ask an expert if you're interested in this kind of thing. I bet there are also Goa Parties in Goa.
