Hi Charles,
Some of the names are confusing.
There is an El San Juan Hotel Casino in San Juan, PR.
For Aruba:
The casino is Royal Cabana Casino at the La Cabana Suites Hotel.
There is an Excelsior Casino (I don't know which hotel).
There is a Palace Casino.
The Hyatt Regency chips say only Hyatt Regency.
The Radisson chips say only The Casino at the Radisson.
I never heard of the
Allegra Resort Aruba, Casino Masaquerade, or
Casino Merengue.
Let me know if you need scans of any of the ones that I mentioned.
There was also a slots only casino in Philipsburg in St Maarten.
There is also a Royal St Kitts Casino.
Let me know if you need scans of any of the ones that I mentioned.
Have you also looked at Ralph Pollack's excellent books and Archie's book on Puerto Rico?
Thanks--Alan.
