Asian mongering trip suggestions

[oldmcdonald]

Hi bros,

I will be visiting Singapore again shortly and will have 11 nights to myself. I like flying and I like bonking, so I want to plan a mongering trip around asia and would like your help with suggestions.

I need to be in China for 3 days so still have 8 nights.

Plans and nights are flexible, but I'm thinking in this order:
Singapore 1 night
Ho Chi Minh/Phnom Penh 3 nights
KL/JB 1 night
Bangkok 2 nights
China 3 nights
Singapore 1 night + most of the day before my flight home.

I haven't been to JB, HCM/PP or Bangkok before so looking for some help on those places. In terms of mongering safety, $$ for girls, quality of girls, which places should I spend more/less time in? Or best to stay in GL :P
I hear HCM could be dangerous but cheaper than GL and I have a soft spot for viets. Not into LB so still worth going bangkok? I only speak chinese/english so language is also a worry
Thanks bros
