Antkim - I would say book now for Aruba. I don't know what fares you've found (or where you are flying from) but it's always expensive. My family goes every year (for about 15 years now). For their January trips, they usually have their tickets by June at the latest. And sadly, the fares from NY are around $850, typically.
So my advice would be to book earlier rather than later. I'm not a fortune teller

but I doubt that fares will dip that much lower if you wait.
Where are you staying? I just LOVE Aruba and I'm so excited for you!!

If you are a newbie there and if you have any questions, feel free to PM me. If I don't know the answers, I'm sure my family will
P.S. I've flown both AA and USair and I have no preference. A flight is a flight to me
