We have stayed at CBR twice and agree with comments posted. Quiet pools are open all the time and I had never seen so many people swimming as I did after 11pm. The main pool is open but no lifegaurds.
No one seemed to be policing the noise level and everyone seemed respectful. But you know how it is there is always one person who doesn't care about others and will be loud. But that can happen anywhere at anytime. Have fun
