Hola Migda!
Gracias por tu pregunta! There are so many things your 3 year old princess can enjoy at WDW!
The first thing to do is decide where you're going to stay. I prefer staying on
WDW property, because of the fabulous Disney Transportation System.
When planning a trip with small children the best thing to do is keep your schedule simple and flexible. Check out all the
attractions and
entertainment to see which your princess will love. It's been my experience that when traveling with toddlers,
Magic Kingdom always takes up most of our time. At her age, my kids loved to meet the characters, so a good idea would be to pick up a Times Guide as soon as you arrive at WDW so your daughter can meet, get a picture and an autograph with all the characters she loves.
Also, consider making some advanced dinner reservations. A character dining experience such as
Cinderella's Royal Table, or a princess transformation at the
Bibbidi Bobbidi Boutique will make her trip even more special.
Remember to bring lots of sun screen, hats and bathing suits because it can get pretty hot!
Have a magical vacation!
