Chapek said on CNBC yesterday that they would not open more hotels than they need to initially.
I imagine (this is pure speculation) that, at the very least, both Port Orleans resorts, Coronado Springs, and the All Stars will not open.
Depending on occupancy levels, it would not surprise me to see Pop Century and Yacht Club join them.
That's all the resorts without a DVC attached except for AoA, which with all the suites would be harder to accommodate guests from (although I wouldn't completely rule that out either if they have trouble filling the DVC rooms with points guests).
I am booked at POR.
