Gaming Loyalty Programs - Station Casinos (LAS) - are they seperate programs?

I live about 10 minutes from Texas Station & Fiesta Station and joined Texas Station when I got here. Last night, I played at Fiesta for the first time and had to sign up for a different card there. I thought it was all one company - do they have different loyalt programs at all the Station casinos?

They have separate programs.

All the "Station" named casinos + Red Rock and Green Valley Ranch (note: Main Street Station downtown is not a "Station" casino) have the Boarding Pass/myCard program.

The two Fiesta casinos (Henderson and Rancho) have a separate program - the Amigo Club.
