My understanding is there's nowhere to eat at CBR right now so I'd give it a miss. Apparently the buses have been dreadful the last couple of years too.
If the food court was up and running I'd consider it - we've been to Disney during plenty of building works and it's never been a huge issue, just a bit of an eyesore.
The renovation of YC is running around five months behind its initial schedule from what I've read, so I wouldn't trust them to run on time!
