Compared to July, February will likely have multiple rides down, the park hours are traditionally MUCH shorter, and you're likely to have entertainment like fireworks on weekends only.
The week of Presidents Day was NUTS last year (the whole week after the holiday), and much of February was crowded when it wasn't pouring rain.
I have been saying all year that I never spoke with as many disappointed tourists as I did this past February, but things are SO unpredictable that this year could be much better (certainly the unusual amount of rain impacted last year). So make sure you have your expectations in check, and hopefully you'll hit low crowds, nice weather, and not too many refurbs.
