A new feature was just been implemented on the Caribbean ChipGuide, identification of the "was" and "became" casinos for that location. For example, if you are looking at the Palace Casino of Aruba page, in the casino information box you will see "Was: Americana" and "Became: Allegro Resort & Casino". If you click on the WAS or BECAME casino names, you will taken to that casino. So far I have only added lineage for the casinos of Aruba, because that information is well documented in Ralph Pollack's "Casinos of The Dutch Caribbean".

Take a look
