Hello, Federico,
How wonderful that you are beginning to plan a family trip to Walt Disney World. I know from experience that it can be overwhelming, so I'm glad you have sent a question our way. Since I believe you may be at the beginning stages of planning, it may be easiest to work with a reputable travel agent or to contact Walt Disney World to speak to a vacation planning expert by calling (407) 939-5277. This will give you the best options to price out different travel packages.
Prior to calling, however, I'd explore the different
Disney Resorts to see which matches your tastes and budget. And of course, we can answer more questions about any of the specific resorts. I'd also order the
free Disney Parks Vacation Planning Video since that you show you more about the resorts and parks as well as
My Disney Experience.
As for the best time to visit, typically if you can visit during off-seasons (not during school breaks or over holidays), you'll find often find the crowds lighter. My dream time to visit is during the first three weeks of December when Disney is decorated in holiday magic, the temperatures are more mild, and the crowds are lighter.
I hope this helps you to begin your planning; please let us know if we can help again.
Happy planning!
