I Need Help Planning A Event?

I'm planning a new year countdown for me and my friends, but I' having problems deciding what to do, we cannot go camping because the girls and some guys don't like the fact that we won't have a shower and toilet, bbq b the beach is a no coz we had enough bbqs to make sure we hated it..., chalets and hotels are a no coz it's impossible to book one, no dinner or lunch coz too boring for them, so ideas pls? take note i reside in singapore... thx loads
