Just got back from 10 days at CBR. I think the consensus among the four families that made up our group was that we'd look elsewhere before returning, perhaps going back down to the economy resorts (we've typically done the All Star Resorts in the past).
I will say that I can see CBR being a very attractive option for certain travelers, specifically:
*Couples, thanks to the very tranquil vibe and pretty scenery
*Those traveling with older children who can enjoy the smaller perks (ex. hammocks on the beach, jogging trail, bike rentals, etc.)
*Those traveling in the "cooler" months when extra non-park walking might be more pleasant
I would not recommend it to anyone with very young children, especially in the summer.
The way I see it, the biggest upgrade from the economy resorts is the scenery. It is definitely very serene and relaxed, and the lake at the center of the resort area is attractive. There are some smaller perks (quiet pools in each area, clear view of nightly fireworks, plus others mentioned above) that add some appeal, but overall the main amenities are just about the same (food court with varied options; arcade; souvenir shop; poolside bar).
To me though, any upgrade is offset by the inconvenience of enjoying many of those amenities. While a 5- to 10-minute walk might not sound like much, it very quickly becomes tiresome to make that walk -- over and over and over again -- after a long, sweltering day at the parks; when you just want a cold soda or morning coffee; with a hot, hungry toddler; or all of the above.
On the day of check-out, if you're taking Magical Express to the airport, depending on the timing you might need to make two separate trips to the Custom House located outside the main circle of resort villages -- once to drop off your luggage/check in for your flight, and another to actually leave. You reach the Custom House either by circling around the resort on the internal bus shuttles, or by walking anywhere from 5 to 20 minutes depending on room location. Most of us longed for the ease of simply walking to the front desk at almost any other hotel, motel or resort.
I did not have any issues with the buses or the number of stops within the resort.
I did like the proximity to the quiet pools and the laundry rooms.
I'm not going to hold it against the resort, because with a very natural setting comes natural wildlife, but I will advise that you lay a towel across the bottom of the door if you don't want an unwelcome guest or two in your room.
