Bro's, I need your advice please!

I'm travelling to Manila next month for work. This will be my 1st time travelling to Philippines. I'll be there for 11 days and will have a further 5 days to myself before I have to return to work in Sydney.

In between the 11 days of work, while in Manila, I'll be using brother @bradpitt's recommendations from another thread. For the 2 weekends in between, I plan on visiting Angeles City.

For the 5 days of free time, I plan on travelling to Ho Chi Minh. Also will be my first time travelling here. Is this the best use of my time?

1. Other than bradpitt's advice on Manila, can anyone else share their experiences and provide me with any punter's advice?

2. Please also share your experiences and thoughts on Angeles City?

3. Do you think that travelling to HCM will be worth it? (Thailand is not an option as it will be too obvious). How's the punting scene? Where do i stay and whats the best way to find WL's? Those with experience, any advice will be appreciated.

Thanks guys.
