this is exactly my fear. I did ChiangMai about 12 yrs ago when it was a real backwater gem and off the mass tourist track.
The challenge with CM is going to be, what do you do with a 6yr old. Even all those years ago, I did the night mkt once and that was it.
There are just so many temples one can be bothered to do as well.
If we go, it will probably be to stay at The Chedi or Four Seasons and just chill out there with the kiddie in the pool. Sounds boring ehhh....but I need to chill out.
Been on the web this morning looking at Cairns too.
