Well, you are asking this question on the CSR thread.
I haven't stayed at CBR, but the reasons we choose CSR are queen beds, great bus transportation, a much better pool for teens (my DD13 ranks the CSR pool and slide only behind the Beach Club pool and slide), sliding doors near the vanity (much better for privacy than the curtain) and good dining choices. We haven't stayed at CSR since the Pepper Market started a buffet for breakfast and lunch - they are a great value on the dining plan since they count as one quick service credit. We usually eat dinner at Pepper Market or by the pool and enjoy both.
