Hi Louanne (my fellow Ontarian!!)
It is busier on President's Day weekend but you will be there a couple of days before and staying for a couple of days after so I don't think it will affect you. You can plan on doing other things such as visit
Downtown Disney,
miniature golf, resort activities (
swimming at your resort pool)
It does get busy in March because so many schools have their spring break.
If you can go the first week of March it is not as busy.
Choose the dates that work best for your family. Take advantage of
Extra Magic Hours for resorts guests, which gets you into the parks earlier or you can stay later.
Try not to worry about the crowds, everyone there is there to have a good time and if you keep that in mind you will have a fantastic time!!
On a side note, your girls would love a trip to the
Bibbidi Bobbidi Boutique or dining at
Cinderella's Royal Table
Please let me know if you have any other questions.
Happy planning!!
Carrie
