Definitely price a 30-day rental at the New Hyde Park Budget office. With either the AARP or Entertainment Book BCD, I'm getting a rate in October of $737 all-in for a compact (not counting optional insurance) per Orbitz. Of that total, taxes/fees are only $121.
Not sure if Budget would offer an even lower price on budget.com for a prepaid on a monthly rental.
The Entertainment Book also has a coupon for $50 off a monthly rental with Budget, but only for an intermediate or larger car. With the coupon, you should be able to get the intermediate for a few dollars less than the compact.
