I find it interesting that everyone seems to have a different breaking point in which they would decide to cancel a trip. For some it’s no pools, for others it’s no TS. Some would cancel if masks are required while others may cancel if they aren’t. Etc. Etc.
For me I think it would be the mask requirement, if nighttime shows were cancelled, and to a lesser degree if there is no TS. I understand that Disney will do whatever they need to do to give both CMs and guests a feeling of safety. If I’m going to spend $6k for my family of 5, my choice would be to postpone our trip until a time when things are more “normal”.
