Sapphire Resorts is the US name of GeoHoliday Vacation Club. I don't know the business model.
Geo Holidays has been in business for over 20 years . they are a legitimate Timeshare Developer .
I would group them with Timeshare brands like : Capital Resorts , Raintree Vacation Club . etc.
TS entities that have less visibility because they are midsize and mid-level.
Geo Holidays owns units within resorts and sells access via points ownership .
They may also have some affiliation agreements with other developers .
Geo H was started in Toronto . They developed & own a number of TS properties in Canada .
I believe they "rebranded " to Sapphire for sales purposes in the last 3-5 years .
Per TUG postings - the Sapphire brand seems to have a sales location in Las Vegas .
I have also seen exchange listed units on RCI .

For any future reader - if you are past the rescind deadline for Sapphire Resorts / Welcome to TUG .
TUG is Timeshare Users Group .
Work on learning how to best use what you bought . It can be done . Over 50% of TUG members bought their first timeshare from a developer and paid full retail - like you did .
Many TUG members then added to their vacation usage and ownership - by learning more and buying more - resale .
