Very Very busy... Its the Daytona 500 time of the year and there are lots of people staying at Disney because hotels in Daytona are sold out.
It is also winter break for schools in the New England area and that means there will be lots of kids.
We have gone the past 3 years and the parks are crowded.
Fast Pass go quickly and lines are long.
Disney also host a cheerleader competion during that time so staying at Pops, All Sports, ect will be over run with kids. We went to the Pops for lunch once and man it was a zoo. Buses were over crowded.
So if you are planning to go reserve your room now!
