I noticed higher rates today when I re-ran a search on Costco Travel. Still hoping to see a better deal in time to rebook, but it's been about six years since I rented at MCO so not sure what my odds are.
As an aside, can someone clarify whether it's necessary to cancel a 'back-up reservation' before the pickup time? I have bookings on both Budget and Alamo for January. Budget is slightly cheaper, but I've seen some posts here about first-time Fastbreak users being directed to the regular line and losing the benefit of quick pickup. If there is even a small chance of this happening, I'd probably go with Alamo since their pickup system looks more efficient. Will Budget try to charge me some kind of fee for not canceling? I'd prefer to hang onto both bookings in case something nutty is going on with one of them and then I'd just take the other.
