To follow up on my experience. I had emailed Disney prior to my cruise and did not get an answer prior to cruising. I went and spoke to guest services the first night. The CM I spoke to was unsure, he went to the back to speak to a supervisor and came back and told us we were good to go, no need to pack, no need for a test at the port. I did let our stateroom host know that we would not be packing up due to sailing on a 90 day recovery letter. When we got back to Port Canaveral we went through customs and walked right back in to check in without question.
