I didn't love CBR either. I had some bad experiences that kind of tainted my view though, I think. The first room we were in had mold in it. We got in late (like probably close to midnight) and the room smelled kind of funny and seemed damp, but we brushed it off because we were tired. Fast forward to the next morning...I woke up with watery eyes and unable to breathe through my nose. We headed out to a park and I felt better within 15 minutes, so I knew it was an allergy rather than illness. I'm highly allergic to mold and my husband did a thorough search of the room - found mold in the A/C unit. I wasn't taking medication at the time because I was pregnant. I will say that they moved us immediately upon request, and our second room was fine.
The other issue we had was the buses. MK opened at 6 AM the day we went. We got to the bus stop at 5:40 and there were a ton of people there. No bus had come AT ALL that morning. We decided to just drive. We passed another bus stop on our way out and there was a large crowd of people at that one too. After our afternoon break, we gave the bus another try. We waited a few minutes, and a bus came, but it would only drop people off - wouldn't let anyone on. Again, we just opted for the car, not knowing how long it would take to get another bus. We used a car for the rest of the trip.
It's a pretty long walk from some of the rooms to the main building. I wouldn't even bother trying to get everyone up and over there for breakfast unless you're in a preferred room. You'll lose too much time. I'd just pack some non-perishables (dry cereal, granola bars, cereal bars, or even pop tarts) and eat in the room.
It's not like I had a truly awful experience, but I've liked all of the other resorts I've stayed at better. I doubt I'll ever go back to CBR.
