I am taking a 21 day vacation to Thailand and would like to visit Cambodia and Vietnam. Is it too much for one trip? What is recommended.
Bangkok is under water now. Not advisable to visit for the moment. Go to Chiangmai instead. That's northern Thailand. In Vietnam, go to Ho Chi Minh City. Plenty to do there. Similarly, i Cambodia, you must visit Siem Reap and Phnom Penh. Great places to visit. Don't forget to bring your camera. almost 8 years ago
How difficult (and expensive) is it to find an iPad prepaid microsim card in Beijing, China, preferably in the airport upon arrival?
You can buy a package from either China Mobile or China Unicom. I bought a China Unicom package for my iPad for RMB300 which comes with a 9GB data. It works perfectly and lasted me about 3 months with normal usage. almost 8 years ago
Mutianyu is great. I was there in May, weather was beautiful then. I walked all the way up and climbed the stairs to the top of the Wall (as far as i was allowed to go). Coming down, i walked as well and i counted the total number of stairs of about 1100 stairs (from just below the wall to the ticket booth at the bottom). Took me 3 days to recover from the muscle ache in both my legs. almost 8 years ago
