It’s interesting to see that OLC is already eyeing on a second Disney cruise line.
They have limited options remaining to expand on land.
It will be interesting to see if the first OLC Disney ship will be a collection of the greatest hits from DCL's prior ships similar to Tokyo Disneyland, or they want exclusive unique offerings (simlar to their recent park strategy) from the get-go, or a combination of both.
Disney Adventure did almost entirely new concepts and offerings for Singapore (the only repeats were Animators Palate, kids clubs, spas and one of the shows), granted they had an entirely different ship design to work with. However, could have repeated concepts like Marcelline Market and 1923 etc but did not, so there was a conscious effort to be unique for the Asian market.
