We just returned from our CBR stay, 7/31 to 8/6.
We got the $75 per night gift card ($450 total) and the Room Only discount rate of around $155, so was an excellent deal! The rebate gift card had a construction Mickey on it that several CMs liked and commented on that they had not seen one before.
We stayed in Jamaica 46 (for some reason in posts and chat I keep saying Aruba 46, my brain must be stuck in my first stay there), parking lot view and just around the corner was the path over to the pool and food areas. We drove down this trip, so drove to all parks except MK. The wait for the bus on our 2 MK days was less than 15 minutes. Jamaica is at the end of the bus stops, but before RD we all got seats each ride without problem.
One note: One day there was a family waiting for the internal bus to get to the front of the resort so they could hop a bus to whisper Universal end whisper. They were there for a bit before we got there and spoke with a driver who checked on that bus for them: turns out there is a single resort loop bus so it takes up to 30 minutes to get around, so if you need it be aware you might need to build extra time into your plan. (That is probably the case all the time, not related to construction.)
(Unrelated to construction: Loved the parking lot view since we could load and unload car right in front of our door. Did NOT like the huge number of mosquitoes hanging around door at all times that immediately flew into room every time you opened it. We ended up ceremoniously spraying mosquito repellent around the door each morning and night.)
When driving around the outer loop, you pass a few obvious construction locations, but most spots are covered with nice decorated fencing, so not very obtrusive at all. Walking around the resort you can see work being done across the water (as others have posted), and see the food court work closed off when you are at pool.
But, in the 6 days we were there, I think the only noise I heard was a single set of medium-loud hammers one time. The day we stayed at the resort and were in the pool most of the day - heard nothing at all. (In fact the 6:40AM lawn mower brigade on one day of the trip was much more annoying and went on for a long while!)
The huge tent they put up for the QS buffet is very nicely done (and very cold!) - however we did not eat there or the food trucks at all so I can't comment in detail on that. (On a given trip we tend to eat only once or twice in the resort. Our kids have severe nut allergies and even with Disney's great handling of things the combination of the buffet style and temporary feel to it, don't think they were too comfortable with the idea of eating there.)
However, DW and I did look around at them and they were very nice - in other circumstances the setup was more than fine and I would have eaten there and not had any problem.
I think my largest complaint: The coffee was just. never. hot. NEVER. Not at 645AM, not at dinner. That includes both the main tent and the mini-market.
While fairly annoying for DW and I, and as much as I like a nice hot cuppa in the morning - if that was my biggest problem, then I'm good.
There was also a truck dedicated to souvenir and store items that had a nice large selection. (In fact, my wife had a wonderful experience there talking to the CM. My wife has been looking for a nice Tink pin, but couldn't find one she really liked. The CM struck up a conversation and they talked for a long time while kids and I were in pool, sharing family stories and things about Disney. At the end of the conversation the CM told my wife she was going to give her a pin - and she gave her the best Tink pin we'd ever seen, a large one with a pixie dust background. Really touched my wife.)
Back to the resort info: The pool area itself was really unchanged.
The mini-markets in the various room locations were good - could have used more selection IMHO, but good. Around the corner from each mini-market next to an ice machine was a Freestyle soda machine - kids loved those (too much.) Every time we went to one there was a trail of kids waiting to refill.
The mini-market was about 3 buildings over - about a 5 minute walk. Not really bad, but a lot of lefts and rights to get there if you keep to paths. (I ended up just hoofing it over to the main tent most times, since I usually went to get coffees about 6:45 each morning and like the sunrise walk anyway.)
There are also a few concierge locations in buildings around the resort, but I did not used them. I only learned about them because I had an issue with how charges were done on my credit card and needed some money to be shifted around to maximize my rewards.
So, the TL;DR: My take away: If you are a Disney veteran and got the $75 rebate and/or room only discount, the resort is absolutely fine and staying there is a no brainer. Aside from the food tent and trucks, everything else when in room areas and the resort is the same, except for a few transition spots.
If I were to add any warning at all: if you go to the resort food court a lot, or if you are a first or infrequent visitor: there may be a bit less magic for you when looking for food, but still more than acceptable.
Again, with the discounts and if you have the rebate: I'd absolutely stay with CBR again.
If I were booking now and had to choose between CBR and Port Orleans Riverside or French Quarter and room rates were the same (with no construction rebate): I think I would go POR or FQ just to have the nicer food experience.
Othwerwise, If I'd already booked CBR I wouldn't worry about trying to move.
Speaking with other folks at the resort - Everyone there was very upbeat about staying at CBR. (Funnily enough, we talked with a lot of other guests and almost without exception everyone was from the UK or France. Same in parks - I think half of the UK was in park this week.)
As a reward for sticking with my long report - here's my favorite resort photo from one of my early morning walks for coffee last week. Hope you have a great trip if you're going!
