Still don't have tix to FL for Pesach? A little shocked at prices?
Another option to look into if you have more than one driver and willing to drive back; fly down one way and drive a rental back.
Alamo, Avis, Budget & Enterprise (and I'm sure others too) all have cars dirt cheap 4/8 one way from FL airports to NY area airports.
Some Total Price examples I've seen on costcotravel.com for 2 days 4/8-4/10
Midsize to Fullsize cars $30
Minivan $60
Suburban $84.
