We like CSR for romance. Take a look at the photos Buzz attaches to his posts. At night the place is simply stunning with lots of fountains, pretty garden areas, etc. Dh and I like a walk around the lake so much, we drive over there for dinner and a walk, even if we're not staying there! While we're not fans of Pepper Market, many are. And, we like Maya Grill, although we stick to a variety of appetizers and desserts and skip the entrees. We think both the Casitas section and the Ranchos sections are lovely. We were there with kids and stayed in Casitas. We thought the Ranchos would be perfect for romance, too. The ranchos have a quiet pool that really as quiet when we were there, plus a desert Palm Springs kind of style that we like. We would avoid the Cabana section, although many like it for convenience. CSR is a large property so there can be alot of walking. We always rent a car, so the fact that it doesn't have "public" transportation doesn't bother us. And, when we stayed there, we thought it was great for driving -- centrally located to everything.
We've stayed at POR as well and thought that was very pretty. But, I'd give CSR the edge over POR. We have not stayed at POR-FQ.
