No one gets sick of questions here. At least, I hope not cos I am Ms. Questions! LOL
Anyways, from what I have seen and read this year, no one can predict the crowds because times that are supposed to be slow haven't been. I would take it as "It's possible it could be busy", LOL. My suggestions? Come prepared. Purchase Ridemax and utilize your time wisely. I will be there in February as well (early Feb. tho) and I am assuming it will be busier than usual but not as bad as Christmas.
Also, for a first timer at DL, most of the time the queues are amazingly well themed. Take your time and check them out. DL to me isn't about how many rides I can squish into my day (but I sure try hard! LOL) but I like the little touches and all of the decorations, etc.
