Based on Trishadono’s reply below, I would maybe have your TA call Disney and confirm that you will be accommodated at the CR tower, even if CL isn’t available. Also have them ask about having your rate reduced to at least the normal rate for a non-CL room in your view category. It’s not likely that there will be discounts for the actual 50th, so even if they can fix it so you are just not paying the CL premium that would be helpful.
That said, it might just be better to get the TA to get confirmation in writing from Disney that you won’t be moved (and if you do, it won’t be to anything but Poly/GF/BLT) and then deal with the price difference later, tho I would still bring up that issue then too.
I just don’t trust Disney to be proactive on this stuff. Better to ensure you have what you want, by having your TA make it very clear what you will and won’t accept now.
You also probably know all of this, based on your posts, I just get cooped up during COVID and like giving advice to people, and as fellow family, I want your trip for the 50th to be the best it possibly can be.
