Yes, four days are enough. You could go to the Oceant Park or the Disneyland, the Victorial Peak, The Stanley market and Hong Kong Science Museum. Actually, this city doesn't have too much tourism destination. It is noted for shopping, of course its food~

Maybe the hotel's full name should be L'hotel Causeway Bay Harbor View. It is located at 18-24 King's Road, Causeway Bay, Hong Kong
