If you like busy, I mean Times Square busy, then Hong Kong and Asia in general is for you. Considered one of the most cosmopolitan cities in the world, HK has tons of famous landmarks and ancient history that keep people coming back.
The Business or Solo Traveler. Why? Because there are SO many people! It can be a bit overwhelming, so exploring HK on your own is probably for the best. Visit Kowloon Walled City Park, explore Wong Tai Sin, and participate in a relaxing Tai Chi session along the waterfront.
