Dear mary,
I am pleased that you'd like to spend you winter vacation in China.
I think Hainan Island will be a right place for you.It's warm in winter.There are many interesting places,such as Tianya Haijiao,which means"the edge of the sky and the rim of the sea",Wanquan River (Dongshan Ridge,Hot Springs,Hairui Tomb).You can swim(fish,boat and dive)in the sea every day,and also there are long white beaches to walk along.You can enjoy the delicious seafood there.The hotels are not expensive but clean and comfortable.llaba26,000 will be enough for your trip.
Hope to see you in China soon.
yours
