Travelling in China is quite easy nowadays and if you stay in three or
four star establishments, you will find western standard infrastructure
(including the toilets).

Depending on what yout kids like to do, you might consider Yangshuo
which in the right season (the rainy season when the rivers carry more
water) is quite interesting and offers a lot of recreation
possibilities.

Shanghai is interesting too. Also consider Yunnan (mainly Dali, Lijiang
and perhaps the southern Xishangbanna region).
