Hello Amanda,
I think all of the Disney Resorts offer a little something to make themselves fun for toddlers. I first brought my daughter to Disney at age three and ever since then, we have found all of the Resorts to be kid-friendly. And you can make your dream of visiting Disney a reality at any budget. Here are my suggestions at each Resort experience:
Value - Pop Century Resort. This is my sister's favorite resort. It has the Goofy Kiddie Spray Area, a play fountain located between the 60s and 70s that kids just love. And the Everything Pop Shopping and Dining is great!
Moderate - Do you have a pirate? Then stay in a Pirate Room at the
Caribbean Beach Resort. Or do you have a Princess? Book a
Royal Guest Room at Port Orleans Riverside.
Deluxe - There's something about the
Polynesian Resort. It has its own Monorail so you can easily get to Magic Kingdom and Epcot, which is also ideal for quick trips back to the resort for midday breaks. There are koi ponds, tiki torches, and the pool has a pretty sweet volcano. And from the Monorail resorts you can watch the Electrical Water Pageant at night.
Hope this helps you make a decision as you plan your Disney vacation!
