For full disclosure, I haven't stayed at BR during the construction. I have stayed there when they haven't been doing construction and I absolutely love it! The pool is absolutely fantastic! It's also fun to walk the grounds. I think it really helps that Florida is a tropical climate so they are able to really keep the resort looking like you are in the Caribbean. It is just so relaxing, but also has a lot of fun going on. I also love seeing the Epcot fireworks from various places in the resort. One night on our visit last summer, my husband and I put our daughter to sleep and then sat outside on a bench with a glass of wine just watching Illuminations. It's one of my favorite memories. I absolutely LOVE CBR.
I do have a friend whose favorite resort is CBR. She stayed there last month and said that the construction wasn't nearly as bad as she thought people were making it out to be and that it was still her favorite resort.
