Club level provides you with a lounge and food offerings/snacks during the day, with evening appetizers and desserts/cordials later in the evening. People stay CL for different reasons and our main reason for staying CL is for the lounge. We like having some place else to go to sit and relax instead of in our room or other parts of the resort. I especially love going to the lounge in the morning as I'm usually the first one up and ready, so it's a great place for me to go and have my morning coffee while everyone else is getting ready

. The food offerings are nice, but they are not to be a meal replacement. We do a sit down dinner every night of our trip whether we stay CL or not. It's all a matter of personal preference, but I do not see it as a bad thing to do the
DDP if you going to be doing sit down dinners anyways (this is, of course, just my opinion).
No, CBR is a moderate resort and does not have CL.
