AIDA Cruises, the market leader in the German-speaking cruise sector, pioneered the "Club Ship" concept in 1996 with the launch of the AIDAcara, introducing a casual, buffet-style environment that revolutionised European cruising. Historically, AIDA has been a proponent of the in-house retailing model, managing its own boutiques across the majority of its fleet to maintain total control over the "AIDA Shop" brand and its popular logo-merchandise. This internal approach allows the line to tailor its product mix specifically to German consumer preferences, focusing on high-quality outdoor wear, sustainable goods, and maritime-themed collectibles.
