Looks like availability due to Spring Break and the pandemic have combined to make it nearly impossible to rent a car this week at MCO if you didn't already have a reservation. I have my reservations, plus I'm National Executive Elite, so I can still reserve -- but will that mean it will be slim pickings in the Executive aisle at MCO?

I'm less worried about this April trip and more worried about June when I'll have my family and a stroller / bunch of luggage with me. Normally I just select a full size sedan (cheapest price for the largest car with my group rate) and then assume I'll be able to find an SUV or Minivan when I get there. But with there being no availability now in April, and articles saying this is the car rental apocalypse because demand is outstripping supply - I'm not sure if I'd be able to get an SUV or Minivan. Should I be worried?

I already reserved a backup Minivan reservation and just cancel it if I can find an SUV or Minivan in the Executive aisle I guess - should be no extra charges or fees with doing that right?
