February is great, just stay away from the weekend of Lincoln's birthday (this year its the weekend of the 10th) and you will be fine crowds wise. Although we went that time in 2006 and even with the crowds it was a great time and we got an amazing deal on Expedia with airfare for four and hotel for five nights for just under $1400 (did not include park tickets, we had ap's). So even on that busy weekend in Feb you can find good deals. Another great, uncrowded time to go (with good deals) is in September, starting after Labor Day (October gets more crowded with fall breaks and Halloween stuff). We have done that a few times, its so hard not to remember those 10 minute standby waits for Space Mtn. in the middle of the day. I'll be thinking about that this June when the waits are 70 minutes or more! That time frame in September I was able to get Paradise Pier for a nightly average of $109 (plus tax) with the stay four nights, get one free deal.
