Hi, there!
 Welcome to planDisney, Jovanni. We're just thrilled you stopped by with this great question!
 Traveling to the 
Walt Disney World Resort with little ones in tow always makes for magical memories. Your heart is sure to melt as you see their sweet faces light up with joy in the theme parks! To answer your question, children under the age of 3 need to be included on your 
Disney Resort hotel reservation and in the total party size for any 
dining reservations. They do not, however, need 
Theme Park Tickets or 
Theme Park Reservations for entry into the theme parks. 
 There are lots of 
benefits associated with the Disney Resorts Collection, but when I was traveling with a baby or toddler, I always appreciated that 
Disney Resort hotels offer complimentary cribs. I loved knowing that my little ones had a comfortable and safe space to rest after an adventure-filled day in the theme parks. A fitted crib sheet is provided, but I was sure to pack a favorite blanket, a much-needed "lovey," and a sound machine. After all, a well-rested baby makes for well-rested parents!
 Did you know there's a conveniently located 
Baby Care Center in each of the four theme parks? It's the perfect place for a quiet diaper change or feeding! 
 I hope this was helpful, Jovanni. Please let us know if you have any other questions about your Walt Disney World Resort vacation! We'd love to help you plan a magical stay.
