I'm not really an expert on this property...but here's what I know. There is a food court that all 3 share, but each has their own pools. Double check that the Courtyard rate you got includes breakfast, because even though they mention breakfast on their web-site, it is something you pay for and not complementary. If you go on the marriott.com website, and pull up that Courtyard property, click photos...you can see the exterior 360 degree view that shows the "circle" and all 3 properties. They are absolutely in walking distance to each other, very close. I don't know if you can pool hop. I work for Marriott, and the only reason I said "upgrade" to Courtyard is that it is considered a level above the Fairfield. It is geared toward business travelers. It will be a little nicer than the Fairfield, but not alot. It depends on if you think the $ difference is worth a small upgrade in hotel features.
