My husband and I are planning our December honeymoon to Thailand and Cambodia, which will include a 3 day stay in Chiang Mai. I'm looking at a couple of hotel/resort options both inside and outside the Old City. I've been told that the Old City can be less appealing because of cleanliness/sewage treatment issues, and that staying outside (we are looking at the Siripanna Resort, to the east of the Old City and just across the river) could be better, especially with easy tuk tuk/etc access downtown. Also have heard that the riverfront is very nice, too.
We live in NYC and have traveled so understand what international cities are like - just want to know what we are in for! Would much appreciate any guidance.
