So how light are the crowds on average? The photo above (by 1Prince2Princesses) shows the park emptier than I have ever seen it. But, then again, I've never been there in February before. Do you still use Fastpass a lot or can you pretty much just go for the normal wait lines without having to wait too long?
I havent seen the park that empty, even the first week of February. But we also havent been there at 10 am. We only needed to use fastpass once and that was for Soarin. The lines are not that long at all to wait. We may have waited 10 - 15 minutes at the most. Never longer than that. The first week of February usually has a lot of cheerleaders there since there usually is some kind of competition, but the crowds are still ok as far as waiting for rides. We keep going that same week so you know it cant be that bad. We made the mistake of going one year at spring break, never again!!! I would rather take the kids out of school then deal with those crowds.
Hope that helps, you should not have a problem with wait times for any of the rides. The only other ride that comes to mind that you may want to get a fastpass for is Peter Pans flight at MK. No matter what time we went, there was a pretty long wait. We even tried to go during wishes thinking everyone would be watching fireworks......I think everyone else had the same idea.
You will love going in February, enjoy it.
