I assume when you say "after BTS" you mean after the floor closes Saturday and before the film festival starts because there is a lot more to BTS than the show floor. There is also dinner with the fish and famous in that time slot but most of us are not fish or famous. After the film festival is the Cayman party with loud music, drinks, more finger food and door prizes.
I was supposed to be at BTS all three days but yesterday I got a jury duty notice for the 21st so now I am not sure :(
