Welcome Mario,
Congratulations on your upcoming Walt Disney World vacation! February is a beautiful time to visit due to the cooler temperatures and generally smaller crowds.
All standard Disney Resort Hotel rooms can accommodate 4 people plus an infant under the age of 3 in a crib (pack-n-play style). Since one of your children is under the age of 3, you may choose from any of the Disney Resort Hotel categories which are: Value, Moderate and Deluxe. Here is a link to view the different
Walt Disney World Resort Hotels. Later when your infant becomes 3 or older you will need to choose a Resort Hotel that can accommodate at least 5 people and they will also need a theme park ticket but for now your 18 month old is "free".
On your reservation you should list all members of your party, including your 18 month old. You will not need a theme park ticket for the infant nor will you be charged extra for the crib but they do need to be included on your reservation.
Thank you for submitting your question Mario. Please let me know if you have any further Disney vacation planning questions. Have a
MAGICAL vacation!
Blessings,
Brenda ºOº
