The success of a hotel can also become a burden. In San Juan in the 1950s, for example, the new InterContinental and its casino and show room, the Tropicoro, featured stars such as Eartha Kitt, Harry Belafonte, Paul Anka as well as Marlene Dietrich accompanied by Burt Bacharach. The island was always overbooked. It became such an attraction that the management was forced to have guests sign a formal declaration at check-in confirming their check-out date and their agreement to leave as scheduled; the hotel manager was repeatedly forced to charter aircrafts, ferrying surplus guests to the InterContinental Embajador in the Dominican Republic. The starlets aside, the political instability in some Latin American countries was a factor for concern, some turbulences and even hotel closures here and there.
