yeah thats true I would totally agree with what your saying, i've been frequently visiting KL 2-3 times a year over the last 5 years because Airasia Flights (SO CHEAP!!) for the transfers to Hong Kong, Thailand and Vietnam my 3 favorite countries, so I usually do a stop over for 2-3 days and just to hit down the KTV to drink and fuck, getting totally wasted, sleep till 6pm wake up eat and repeat (I'm crazy).
The advantage of KL is your able to communicate with English which is reason why I tell all my boys to visit. This solves 90% of the problems in a foreign country, and with the help of places such as 'beach club' and 'thai club spending' things cannot get anymore easier. Having the option of Thai, PRC, Viet and Russian also other nationalities. Paying $30aud for ST and $120au overnight you cannot lose not mentioning the abundance of Massage places like Saboon, Online Escort Services you can easily locate with the help of your friend google. So if your just looking for a cheap punt, then KL is recommended. I will probably do a guide on KL when I find the time but if you look around there are plenty of info online already.
Vietnam on the other hand is very tricky for foreigners especially if your white you'll definitely be taken advantage of (sorry but thats just the culture) and it also goes for any non vietnamese (kiu/hoa) that doesn't speak any vietnamese or have family there, you'll be left with the old and uglies and be charged more than double the price.
As long as you have a friend or know a local you will definitely have a way better time and find it is much cheaper and better quality girls than KL. Also having the advantage of similar websites to Hong Kongs sex141 database with thousands of girls to choose, providing fetishes and special services. Hairwash is just a whole other level from your usual RnT, awesome food and abundant things to do. (if your Old Gen asian you'd understand)
I spent 10 days in HCM the last time I was back for business and spent no more than $50aud over 2 days.
I was visiting a High-end 'Hoc Toc' for massage and hairwash (no sexual service provided).
This shop has English speaking girls, not perfect but sufficient as it is popular for Viet Kieu to visit (Viet Kieu = Overseas born Vietnamese usually American or Aussie). There I met the most gorgeous girl, not just a face fit to be a Jpop idol but also got a rocking body similar to Iggy Azalea. So I got her number, talked and payed her a second visit the next day and took her out to dinner, later that night we got drunk and spend the night together.
The next 3 days we met up after she finished work and went on dates ending back at her place.
She took the next 3 days off and went on a trip together to Da Nang paying for flights and expenses.
This whole GFE experience 7 days of bonking and I spent around $300-$400aud on this girl(gone in few days for KL) is something you can't find easily in other countries. This is not a hit and miss but happens for me and my mates every time we visit as the girls hope to find a husband/bf preferably Taiwanese, Korean or Viet Kiu. Caucasians aren't as popular here compared places such as Thailand, Phils and Indonesia. Another thing is, girls in HCM are very fair white skin and very pretty, resembling, Japanese, Chinese and Koreans because with dark skin you are look upon as lower class, poor, farm girl and would never find a good husband.
Overall, this is my preference as an Aussie Born Chinese, I would strongly not recommend Vietnam unless you speak some viet or have a guide with you as you will miss out alot, getting ripped off only leaves a bad flavor.
Majority of the viet girls working in KL are from the poorer regions of the north, usually introduced by a friend from the same village because they can make money. You can tell by the tan and the heavy makeup. You have to be especially careful because I know for fact they aren't educated about safe sex and carry STI's. Not to mention basics such as oral hygene, waxing or shaving legs and use of vagisil. I found it really shocking with the amount of girls in KL who don't mind going bareback. Don't get me wrong, the quality of girls is amazing, you'll find alot of beautiful young girls in their 20's, based on tales and personal experience if your going to be playing with freelance such as ones from Beach and Thai Club, you should have a few things to keep in mind: (this is anywhere in general, but through word of mouth, some bros made friends with STI from KL)
1. Never go bareback
2. Never Kiss or oral
3. Have disinfectant ready such as detol shower gel for before and after or any other protective measures.
4. Play smart, look after belongings and check if your followed, always check her ID and take a photo for security
Just remember these girls are all on tourist visas.
so in reply to your post, I agree many quality girls are indeed in Malay and SG (sad to see the decline of cantonese speaking locals), if your only visiting for punts then you've made an excellent choice. Price in HCMC is subjected to nationality and having a vietnamese speaker is a huge advantage. Sadly to say being robbed can happen anywhere in asia if you decide to go for the cheaper options going in an unsafe environment is just plain stupid, you should find many articles online about KL beach club and thai club, getting chloroform or organ harvested by Indonesian gangsters, and in terms of safety, HCMC is a much safer than KL, difference is HCMC has higher rate of petty crime, but KL has more stabbings, organ havesting and violent crimes (not saying theres that much to scare). Yes alot 4star+ hotels in don't allow WL but you can still find alot of cheap yet very clean and safe ones, PM if need advice. (remember the star system is based on facilities and not on service or quality) Everytime I visit I stay in Airbnb apartments, and I always have friends when they hear I'm going vietnam they would like to visit with their GF's Wifes or family and they were perfectly happy with the 2-3 star WG friendly hotels I got for them. Also majority of the hotels in VN has a self rating system and is not the international standard. Even if you were to stay in a 4-5 star hotel, I don't think you'd be stinge to pay an extra $5-10 bucks to open a room in a lower star hotel for the lady. My recommendation is open a room in any hotel near Zen Plaza D.1 Nguyen Trai Street. It's close to everything from Pham Ngu Lao (foreigner street aka redlight district) all the clubs and the Markets.
