We just got back from a 5 night stay CBR. Overall a positive experience that accompanied a great trip. We didn't spend a lot time at the resort, but the rooms were clean and it was quiet. A couple things of note:
We were in Aruba, which is the farthest bus stop. Generally not a problem for us. We aren't rope drop, early morning extra magic hours people, unless there is something we want to do. The only EMH we hit was Animal Kingdom. We got to the bus stop at 7:30 to see a bunch of frustrated people who told us two full buses had already drove by. Full buses still have to drive past Aruba to turn around. Understandable move because of the current layout of the resort, but it definitely added a level of frustration. At 7:50 we just decided to call a lyft and got there by 8:10. If I had read here earlier I would of known to make our way to an earlier bus stop(Martinique, old port royale) you can walk or take the internal shuttle.
We also all agreed the buses seemed to take longer than at other resorts we've stayed at. This could be because the path the buses take to get in and out of the resort is longer due to the construction, but I don't know for sure. Overall, I'd recommend either giving yourself plenty of time to get places or have an alternate form of transportation.
Every CM we interacted with was extremely friendly and helpful. The resort is essentially a construction site but they are doing everything in their power to accommodate and help guests.
I think our best example for all these points was how we missed our Magical Express. We attempted to leave the Magic Kingdom over an hour before the "fifteen minutes before" time but the bus did not show up for almost 45 minutes. Since the park buses don't stop at the custom house and you currently cannot walk there from anywhere on resort property, you have to get off at a village bus stop and wait for the internal shuttle. We got off at Martinique 10 minutes before our scheduled departure time and an internal shuttle arrived shortly after. However Martinique being the first stop of the six, we didn't reach the custom house for another 10 minutes to see the Magical Express had already left . We went into the lobby and explained our situation(we had also called the lobby from the bus and they told us to come to talk to them if we missed it.) Quickly someone called magical express to see if they could get us on the next bus, but that one was full. To my pleasant surprise, without us asking, they offered to call a Taxi and provided a Taxi voucher to comp the ride. I have never heard this done before so I would not count on it happening again, but I was very grateful they were able to assist us.
Overall, I thought the stay was worth it(especially for the gift card.) If I were to do it again I'd request a room with a closer bus stop, or even bring my car.
