SFX

The San Francisco Exchange Company (SFXC) is a vacation timeshare exchange company, similar to other exchange networks like RCI and Interval International.

Here's what that means:

Timeshare owners who are members of a resort affiliated with SFXC can deposit their timeshare week into the exchange system.
They can then "trade" their week for a stay at a different resort in a different location or time, depending on availability.
SFXC was known for having a more boutique or flexible exchange model, often catering to smaller resorts or independent owners.

However, it’s worth noting:

SFXC has become much less prominent, and many of its functions or affiliated properties may have been absorbed into larger networks.
If you’re dealing with them now (e.g., in paperwork or ownership), they may be operating under a new name, have been acquired, or no longer be active.
