Back home...wound up using the Alamo reservation I had, which was a compact for about $114 total for 5 days (was a weekly rate).
A few comments:
The Alamo compact aisle had several Nissan Versas; I also saw a Ford Fiesta and even a Fiat 500. Almost went with that, but I wound up taking a Mazda 3, which I was happy with. Pickup was about 10:30 at night; I'd say there were a total of about 10 compacts to choose from at that time. Sorry, I didn't observe what were in the other category aisles.
Gas prices: I think many of you already know this, but just as a refresher: there are some gas stations practicing what I would call predatory gas prices near Disney. For example, on SR 535 (Apopka-Vineland Rd.), I saw one station that was $3.689...that's fair, but they had a 90 cent surcharge for credit cards ($4.589). There's also a Mobil station at the intersection of I-4 and SR 535 (near Crossroads Plaza and the Hotel Plaza Blvd Disney entrance) that was charging $4.899 a gallon. The worst I saw, as usual, was the Shell station on Vineland Ave (near the Marriott complex and Orlando Premium Outlets) at $5.999 a gallon. Yes, 6 bucks a gallon. These are all rip offs, obviously.
The Hess stations inside WDW were $3.589 yesterday, a Shell/7-11 at Palm Parkway and SR-535 was a few cents more. The lowest I saw was a Hess on SR-536 (World Center Dr - that's the way you would return to MCO if you're leaving from Epcot, using the Greeneway (SR-417)) was $3.569.
I didn't get to the US 192 side this trip, so I don't know what they're charging out there. Just be careful and watch out for surcharges for credit cards. Frankly, I'd stick with the Hess stations - no surcharge at all.
Tolls:
This may be unchanged, I don't remember. On the Greeneway (which you would access if you use the South Exit from the airport...which I would recommend if you're anywhere near rush hour), it can vary where you exit, but in my case (exit World Center Dr. 536 to 535) there were two $1.50 tolls.
