Car Hire at MCO

Hi all, can I ask for some more advice please!
On our trip to MCO this year with Virgin all went smoothly until we went to pick up our Hertz hire car. We had booked it months in advance online in the `global sale' fully inclusive with insurance etc paid in full upfront. We had to then wait at the airport an appalling 3 hours for our hire car, no apology. We waited in a line of others basically for cars to be returned before they could be released. We've hired previously with Alamo and Dollar and have never experienced a delay, we are usually sorted and off within 20mins max. Having travelled with our two toddlers and had a 3hr drive to gatwick and 9hr flight we were in good shape until the 3hr delay for our hire car.... very keen to avoid that on our next trip!! n(
Any tips on the best options?, I think I've read on here you can pre-buy tokens and skip a line altogether? Think we will need a SUV or similar ( 2 toddlers, buggy & cases).
To add to insult, Hertz then overcharged us on our fuel (we paid upfront in the package, but were charged again (at a high premium) on returning the car). I've since got this refunded after several months and letters! Offered us $50 coupon off our next rental with them as compensation for the 3hr delay! ii) We are #1 Hertz club members, but not Gold club members (so can't go straight up to the lot and collect).
Grateful for tips, thanks
