My parents are considering a vacation to either CN or CSA for their 25th wedding anniversary. My father has trouble getting around as he has a lift in one shoe. My husband and I have been to CTI and CSS and know that CSS is very hilly with lots of stairs. I'm just wondering between CN or CSA what people would recommend? Is one smaller than the other? Are there lots of stairs at either of them? The beach is also important to them, so any suggestions on which beach is better? Thanks for any help!!
