Planning trip in hong kong late dec jan 2015 with two daughters 17 and almost 14

If the Disneyland is your only destination in HK, it is fine to stay in Disney Hotel. If not, you are suggested to stay in another hotel in downtown area such as Tsim Sha Tsui and Central, because the Disney Hotel is very costly.

Generally, you can handle the Great Wall tour by yourselves. The Badaling Great Wall in Beijing is the most popular section. You can fly from HK to Beijing first and then take a taxi to get there directly. If you want to ensure everything going smoothly for your Great Wall with no hassle, join a tour through Travel China Guide, who arranged my seven days trip in China last year. You won't be disappointed.
