Juding from the number of customers in Hong Kong, which I visited last year, It will be difficult to expect more customers than estimated.
The biggest problem is expensive entry fee of both Disneyland. When we compare entry fee itself with other countries', it's not expensive.
But, when we consider the prices in China, it's too expensive.(Though prices in Hong Kong is higher than those in China, population in Hong Kong won't make ends meet ,and then have to expect Chinese customers.)
