Hi there Kristi!
I would first check to see which park you are planning to attend. Most of the Child Care centers are located near the parks and it would probably make traveling back and forth from your resort to the center a little easier. The centers are listed below according to closest distance to Disney's Coronado Springs Resort. Yes, reservations for your child are typically required. Sometimes, walk-ins could be available on a first-come, first-served basis. To make reservations, you will need to call 407-WDW-DINE. Here are the locations according to distance from Coronado Springs with the resort's local number.
Yacht and Beach Club (Best for Epcot and Hollywood Studios)
Sandcastle Club
(407) 934-7000, ext. 6191
Animal Kingdom Lodge (Best for Disney's Animal Kingdom)
Simba's Cubhouse
(407) 938-4785
Wilderness Lodge
Cub's Den

When making your reservation, double check with a Cast Member or Concierge at the resort about transportation to and from the Child Care center to make sure you take the best and quickest route. Thanks so much for asking the Moms Panel if you have more questions, I'm always here to help! I hope you and your family have a Magical Time at the Walt Disney World Resort!
