CSR is home for me. I've stayed at POR many times (many times in the alligator buyou and many times in the mansions, but never a Royal room and FQ once.) There are selling points for both POR and CSR.
My boys loves the fishing at POR. They prefer the Dig Site Pool, snack bar, and entertainment in general. I miss Yeehaw Bob. The Rix Lounge certainly isn't that kind of family type entertainment.
I love CSR in the evening. The resort in the moonlight takes on a whole new ambiance. I could walk around the resort all night, especially the Casitas. The water and the lights are so beautiful.
The guacamole is my favorite on property. While the Pepper Market is so uniquely different, I actually like it. There will be at least one fajita with my name on it. Gelato at Café Rix is a nightly routine too.
We stayed at CSR the first year it was built. One tradition that has followed since our first stay, is the Opening Pool Ceremony. My kids love the trip down memory lane as they chant and the water fall turns on. There were times in each of their lives when they each thought it truly was magic.
I like staying at other Disney resorts, but I always seem to come back to CSR eventually. It's home for me.
