OP Here.
I'm so disgusted with trip planning right now. I've searched countless options and am really discouraged. Part of our "problem" is that our arrival date isn't flexible. We booked through RCI so we need to arrive on Saturday, July 21. We live within 15 minutes from our local airport and would prefer of course to fly out of there second to Bloomington. I was hoping that Allegiant would announce Peoria to Sanford/Orlando flights. I even asked if they might do that on their facebook page and was given a reply that it wasn't a plan at this time, but thanks for the feedback.
I missed the $87 each way price out of Midway. Now I'm looking at flying down on Allegiant to Clearwater/ St. Pete and flying back up on Delta. I'm also incredibly discouraged by rental car prices. The cheapest I'm finding (with coupons and discounts) for a mid-size or larger is $400.

The prices right now (not counting bags on Delta) would be $901 for the three of us. That's for nonstop to Clearwater/St. Pete from Peoria and one stop on Delta returning. Allegiant added flights to Sanford from Moline. I was hoping they would bring back the Sanford/Peoria flight.
I'm to the point that I wish we wouldn't have even booked our rooms. Flights and car rental prices are so high right now that I could cry.
I read an earlier post that Clearwater PIE airport is about 90 min from WDW. Can anyone confirm this?
