Hi Scott and welcome to the Disney Parks Moms Panel!
I have traveled to the Walt Disney World Resort during February for the past several years and I think it's an ideal time to visit. When you arrive at
Disney's Pop Century Resort you will be able to check in, even at 9 a.m. You can actually do Online Check-In before you even arrive! You may check-in but your room may not be available until 3 p.m.
If you arrive and your room isn't ready, you can leave your luggage with bell services and find a way to spend your day. Sometimes we head straight to a park and other times we visit Disney Springs to see what's new. We've also been known to pack our bathing suits in our carry-on luggage so we can spend our check-in day by our resort pool.
However you spend your first day, I hope it's the start of an incredible vacation! Please let us know if we can help you with any other questions.
Wishing you a magical day,
Amy H.
