The Golden Tulip was the name of the hotel. The casino was called the Aruba Caribbean Casino.

It was never the Sheraton, though. The Aruba Sheraton was next door. It's now the Riu.

Hotels:

Aruba Caribbean July 18, 1959
Golden Tulip November 1, 1986
Radisson 1993, I believe
Hilton July 15, 2015

Because the casinos are often run by casino management companies, the dates for casinos are not always the same as the hotels they are in.
