Last Day to book 4 for 3????

[d96j97]

Does anyone know if they still honor the entire week savings if you book the 4 for 3 special beginning the last day of the promo...I believe March 24th? We don't have spring break until then and would LOVE to go but can't afford a full 7 days without a savings. I was hoping to book my first day on March 24th and go 7 days from there. What do you think? Thanks to everyone in advance for your help.
