We rent a car from MCO at least once a year. Prices for this summer have been definitely higher than norm. In the August car rental thread, many of us were seeing higher prices this summer.
I recommend checking daily (I also use Costco) and even did this before COVID, I usually end up changing my rentals at least five times, lol.
Right now I have DH booked for a car for his trip to TPA for 5 days in October that was hovering around $200. It dropped down to $167 one day and I grabbed it and it was up again by the next day. It's been sitting at $214-221 now for days.
The kicker with our trip to WDW last month was all the flight changes. Even if you find a good rate, if your flight is moved, it throws off everything else. About 2 months out, you might want to look at different scenarios of what your airline is currently doing with cancelations (and if using Costco, you can book a couple of different car times and easily cancel the one you don't use).
