I wonder just how much the 4th night free hurt Citi's profitability on this card. Were/Are people actually using it? I for one used to maximize my bookings at all-inclusive resorts, which cost them $600+ a pop. Yes, there are commissions on the balance of the stay, but we used to do many long weekend stays of just 4 nights.
It seems like Citi stripped the card of many useful benefits, but preserved the 4-night free perk to differentiate it from the rest of the pack.
