Euro Disneyland faced many issues when it first opened in Paris due to failing to properly analyze the European market. Some key failures included not accounting for cultural differences between Americans and Europeans, such as Europeans preferring longer vacations and not liking to wait in lines. There were also many operational miscalculations, such as narrow parking spaces and not allowing wine in the park initially.
