I live two blocks from the South Courtyard, it won't really matter if you stay North or South because there is alot of stuff within driving distance. I think the South is brand new (or at least built sometime this year.) Right now is a good time too because usually during the summer the South one is smack in the middle of all the activity and you might not get much sleep. Its noisy on the beach front in the summer. (Even at my house I can sometimes hear the music and noise pretty well.) Enjoy your stay! The weather is really pleasant right now, but a light to med wt jacket is definitely needed for a.m and evening.
Stayed at the North Courtyard in Oct. Got a larger suite which had a larger balcony and separate bedroom. Breakfast is not included. Nice place althought the South location is closer to more restaurants. Have also stayed at the Springhill which is newer and very nice. Didn't care for the Fairfield.
