Malaysia? Anyone been? Kota Kinabalu?

[thehabit 420]

Im planning on going there in Jan. I currently live in Guangzhou, and will be traveling with 4 Chinese girls. Ill basically be with just my gf most of the time though.

Anyways, before I knew anything about it, I told my gf, yeah Im down to go, cool.

My questions are...

1.) Is it safe for an American to travel there? should I avoid mentioning the fact that Im American, and say Im Canadian if any1 asks?

2.) Besides some of the best beaches in the world, what else is there too do?

3.) Whats the weed situation? Should I just not even bother looking for safety pre cautions?

I dont know anything about the place besides just some brief reading on the internet, so any Info would be cool.

Also, Ive never been exposed to anything Muslim. I know Malaysia is primarily Muslim. Is there anything I should know, so I dont dis respect someone by being ignorant?
