I know that CSR is beloved by many. This is strictly my opinion. I was very glad that we switched from CSR to POR. You must understand though that I like woodsy, wooden, free form, lush lanscaping settings.
We went in the summer and my major reason for switching was that I thought the theming of CSR would seem "too hot & arrid". To me CSR was very open not much shaded paths. The walk around the lake seemed long. Maybe because it is open and you can see the whole lake, unlike POR where you don't visually see it all. CSR didn't have many bridges crossing the lake so you would need to walk around (though I do understand they now offer internal rides on carts).
I thougth I'd be wowed by the pool and I wasn't. I really came to feel this vacation how I truly like free form design - not geometrical.
We did not at all like the Pepper Market setup. At 8:50 in the evening there was a line of people waiting to get in to be seated. My DH said no way would he have enjoyed that. Their lounge seemed to be an open air type lounge. I like the dark coziness of POR - I'm a corner type person.
I just really liked the quietness, lush landscaping of POR. I like the various textures you experience at POR. If you sit outside the Riverside Mill there are cobblestone walkways, wooden walkways, decorative cement, the rope fences around the marina. I enjoy all the textures (weird, but I now realize that what makes POR appealing to me). For me POR is was very relaxing.
CSR was loud when we were there. My husband said he did not like the wide open feel to CSR. I did like their gift shop however.
I've learned that I'm a WL/PO type of person. Natural landscaping and wood. I'm not too attracted to beachy stuff though I do appreciate the various theming of the resorts.
I might feel differently if I was there in the winter months but overall I will stick with PO.
You may very well like CSR if that type of theming appeals to you. Enjoy your trip. The villas look lovely.
