Stay away from Malaysia. Heading north to Thailand or south to Bali but not Malaysia.
1.) Its an Islamic country, so the population doesn't party.
2.) Alcohol is super expensive, see #1, its against their religion.
3.) No hot chicks since they all like to wear head scarves and burkas.
4.) The Indians, Malays, and Chinese all hate each other; so much so that they have 1Malaysia ads around town to promote harmony.
5.) Terrible public transit system in KL. Terrible.
6.) SLOWEST INTERNET IN ALL OF SE ASIA. <== this one's the killer.
-Been in Malaysia since January 2015.
What a BS.
1. Yes, it is an Islamic country, but about 40% of the population isn't Muslim. Plus, the country itself doesn't really follow Islamic guideline. Nightlife in Malaysia wasn't so bad.
2. Price of alcohol in Malaysia are at decent price, not too cheap, not too expensive. Unless if you're going to some 5 star nightclub. Compared to Bali or Thailand, yeah I agree it's expensive.
3. Wrong. About 60% of muslim in Malaysia wear scarves and burkas. Like I said, about 40% of the population isn't muslim. So there's more than half of the population of woman not wearing scarves and burkas.
4. Nope, not all of them hate each other. Like pinguspy said, "Just typical racist hate between white and black in U.S". There's still a lot of nice people around.
5. Terrible public transit system in KL? Idk what are you comparing to, but for southeast asia, public transport in KL are quite good in my opinion. Traffic in the city are always sucks. Bali, Bangkok, Singapore, are all the same.
6. I don't know if you lived in a jungle or what. Most places in KL have a good internet connection. May not be the fastest compared to worldwide, but for KL, totally not slowest in SEA. Decent internet speed in my opinion, and you could get high speed internet connection from some ISP.
Tbh, I don't really like my country very much, but most of the thing you said are bullshit.
To OP, Since you're looking for nightlife and nice beach, I suggest you head to Bali or Koh Samui. There's some clean beach in Bali but a bit far from the city, about 2-3 hours drive. Beaches in the city (Kuta) aren't clean at all same goes to Koh Samui. You can rent a decent house in the city for around $500-$700 per month. Alcohol are really cheap, you can get one can of beer for $3-$5 in 4-5 star nightclub. Honestly, I don't think there's any nice beach with nightlife especially in SEA. If there's a nightlife, the beach won't be clean.
If you're still heading Malaysia, and looking for alcohol for a low price, ask some local people to help you, there's a lot of tax free liquor store all around the country. If you're visiting KL, I know some tax free liquor store, price aren't much difference with Thailand or Bali.
Plus, most of the beaches in Sabah and Sarawak are clean. Not sure about nightlife.
