They didn't tell us they were closing at 5 until that afternoon while in Epcot. That was fine - I don't have an issue with that. What I did have an issue with was that I asked at my hotel what I needed to do to prepare and we were told to not worry about it, that they would let us know if there was anything we needed to do. I even asked specifically about food and was told I didn't need to do anything. That didn't sit right with me so I ignored it and did quickly pick up some food. They announced that we had to stay in our rooms at a certain time and could not leave. This was at POR so we couldn't walk to the lobby. They announced we could go buy overpriced food before then - which we bought a little of but they were already out of some items and completely out soon after we went through - so some people got nothing. (I wouldn't have bought any had I known as we had enough to get by on. I knew when they were out of all since there was a recording on our phone). They told us to stay in our rooms until they told us we could leave - which they didn't do. We left when the travel restriction was off of Orange County even though POR still wasn't telling us we could leave. For check-out, they didn't have enough people to check out - which is understandable since employees needed to go home too. But the generic Disney system was also overloaded and waiting an hour didn't get us through. (We finally gave up and didn't officially check out). There wasn't an automated check-out that we could do. I'm not sure why we weren't able to do that. My biggest complaint is that I was asking them specifically what we needed to do and they were telling us nothing. It wasn't just me they were telling this too, as there was a recording telling us that as well. They should have been telling people to get food ahead of time at an absolute minimum.
They also weren't helpful how long we could stay. We were supposed to check out the morning of the hurricane. When I asked them the day before if we could get a late check-out due to the storm, we were told no. It wasn't until Orange County's travel ban that we were allowed to check-out late. (Though, as mentioned, we weren't able to do the official check-out process due to not getting through on the phone and the line at the desk being out the door).
I didn't like how they acted like life goes on as usual in the Disney Bubble until the last possible moment.
We didn't deal with refunds but I do know others who did and that worked out well, though understandably, quite delayed. Our main issues were with how POR handled it specifically.
