both days also fine, but how about the timing?
from the last experience, the game last about 2 hours max as
fatigue come into play, plus the $$$ to keep purchasing of ammo
b'come more siong.
my feel is that most prefer to do it during day time, either in the
morning or afternoon. 
can i suggest we start at 1pm, 2 hours later we complete the play,
we can go for a swim(non Orchid member can use the pool?). Damn hot
and sticky after the game.
