Kinda of agree on the statement. It is difficult for attractions without a historical background to be a continuous draw. Something bigger and more gimmicky may just take over its place.
A tourist only has a limited time to visit a particular city and they will be more interested to visit the "more gimmicky/I can go home brag to my townfolks" attractions. Seen in this light, the ranking of tourist attractions is perhaps a good factor to determine if an attraction is a continuous draw. Maybe VB can start tracking the ranking of Straco's attraction. We could see the correlation between the visitorship and ranking.
In addition, the fall in aquarium visitorship of Straco's attractions could be due to the opening of Chimelong Ocean Kingdom Park in mid 2014.
