Hi Nicole!
Thanks for your question. A February
Disney World trip sounds fantastic, and is typically one of
Disney World's non-peak periods to visit!
This is what Disney officially says as it relates to strollers:
*Strollers larger than 31” (79 cm) in width and 52” (132cm) in length are not permitted. Stroller wagons are also not permitted.
*Strollers are not allowed on escalators. Use of strollers is permitted on elevators and ramps, available at certain locations.
*A child must be removed from his or her stroller while riding on a parking lot tram.
*Do not leave personal belongings in an unattended stroller.
*Strollers may be moved by a Cast Member due to operational needs.Using Disney's measurements as a guide, you'd have to compare what they have listed to the dimensions of the Graco double-stroller you're looking to purchase. If it's within Disney's noted dimensions, you're good to go!
It's also worth noting that
Disney offers
Stroller Rentals in both the single and double stroller variety, if renting is something that may be of interest.
Hope this helps. Have a magical day!
Terry
