Indochina Backpacking Tour Itinerary + Expenses (Thailand, Cambodia, Vietnam)

Every time I visit my blog I feel like all the backlogs sitting on my Travel folder is haunting me and begging me to expose them to the interwebs. But I don't know why I've never found the time to do just that until now. Soooo, this is me trying to slowly sync my blog with my life starting with a 6-month overdue post.
I went on an 11-day Backpacking Trip with two of my bestest girlfriends from high school on my mid-year break last June 2014. It started when my NZ-based friend Catrina, messaged me on Facebook last January saying she will visit the Philippines during her summer break and would like to go on an adventure. The next day, we stumbled upon a Cebu Pacific seat sale, and off we book our tickets to Thailand and Vietnam (5 months before the planned trip!) . We had already planned on taking a bus or train from Thailand to Cambodia so there was no use in booking an extra plane ticket to or from Cambodia anymore. My other friend Maica booked her flight a few months later for almost twice the price of our ticket.
You would actually be surprised that this whole trip cost me just as much as my 4D/3N HongKong Tour last year. And if I'd have to choose between the two: the city and lights or the laid back backpacking, I would personally go on another Indochina Tour again. I made this itinerary with the help of various posts I stumbled across the web and with hopes of me being able to help others as well, I'm sharing with you our itinerary along with a summary of expenses and additional comments based on my firsthand experience.
