Everywhere is definitely a place of opportunity. But since Sentosa is so big, I just wanna short-list a few venues that most people do their portrait photography. Palawan's beach bridge is one. Anything else?
Hmmm... i think u need to specify a theme? Models in board shorts, bikini, etc... Or those jungle wear kind of theme? Cant be bikini gals in jungle trails rite? and vice versa. Jus some of my personnel views
Rasa Sentosa rooms in my opinion, small, grossly overpriced >$450 (17% TAX, peak season rate varies), Old CRT tv (wasn't even working properly), etc. Did 2 events there, no thanks.
Spots would be the biggie tree near the golf course, innerside of siloso (old buildings, etc), equator side of the island, beach near Dolphin Lagoon etc, etc
