Okay folks, here's one to try. I just got an email from Budget for a "Jessica's deal". Its supposedly only thru February, but I'm seeing one decent rate that works for my dates at the end of March.
Start at budget.com and use a BCD of D726100 and coupon MUWZ018 . Put your dates in and see what happens. In my case, it barked at the dates, so if that happens, remove the coupon code (MUWZ018). Resubmit it if the coupon didn't work. The rates I got back were almost all bad, with the exception of a weekly $200 rate (that's base, about $270 total) for an intermediate SUV. While not spectacular, that's a lot better than what I've been seeing lately. I happen to still have an Alamo car a little bit less so I'll stick with that. Also, I haven't tried it, but if you have some other Budget coupon codes that do work, you might get lucky.
Again, the codes I mentioned above are definitely public with no strings attached, so go ahead and give a try. The coupon is also electronic only, so they won't be asking you for it at MCO.
Good luck...hope someone finds something...
EDITED: Actually the "Jessica's deal" appears in an orange box at the bottom of the main Budget page and uses the codes referenced above. If you go this route, if it says it can't use the coupon, clear out the coupon code and resubmit.
