I'm planning a trip through Asia in June and July of next year. I'm starting in Beijing and planning to go to Tokyo, Seoul, Hong Kong, Vietnam, Cambodia and ending in Bangkok. Any recommendations would be amazing, especially regarding places to stay? I will be travelling with one other girl and we are both in our early twenties. Thanks!

Try Trip Advisor.. they have great recommendations of where to stay and what activities to do

I did a very similar trip this last spring.
As for places to stay, hostels are a great place to stay. Lots of people to meet from all over the world and certainly very economical.
I'll recommend some of the hostels I stayed at:
VIETNAM:
Hanoi - LIttle Hanoi Diamond

If you want to be a bit inspired, I wrote a travel blog

I really really recommend the Golden Temple Villa in Siem Reap. Free tuk tuk pick-up, free delicious lemon tea drink upon arrival, free massage, excellent service, and very delicious restaurant in the guesthouse.

If you are going to Vietnam then Hoi An is a must place to visit. With Cambodia…Visit Angkor Wat in Siem Reap..it is just so amazing to see.

Just be safe.

Thanks everyone!

Word of advice about Japan. You will not be able to use your bankcard at any bank machines except for ones at 7/11 and post offices.

Yes, so true!

Seoul -
Ultari Guest House super kind hosts and I met awesome friends

Seoul- backpackers Korea if you don't mind hostels. Amazing service with friendly host, good security rooms and meet fellow travelers from different countries!

Rambuttri Village Inn great place in Bangkok close to Khaosan Road, but not noisy! Also walking distance to Chao Praya River to catch the water taxi to The Grand Palace, Wat Pho, China Town and Taksin MRT Line.
