We took a trip to Orlando for my little sister's wedding back in Decemeber. On our way out of town, we stopped by Disney World for a couple of hours. The Little Dude is a HUGE fan of all things Disney. Even though we went on "the coldest day in over 20 years", we had a blast.
To a 4 year old, Disney World consists of characters, parades and the Mad Hatter's Tea Cup ride. We made all 3 of those things happen for The Little Dude. Even threw in a bus ride and a monorail ride or two.
We'll go back to Disney when he is older. I think 4 years old is still way too young. It's really expensive to get in, plus a ton of walking and waiting in line is involved. I am an adult and even I have issues with that much waiting. However, I am SO happy that we had the opportunity to take him at this age as the "magic" of Disney was overflowing!
