Hi Raechel!
You have chosen a great time to visit Disney World! There are a couple of special events going on during your stay.
The first one is the
International Flower and Garden Festival held at Epcot. This event is held daily from March 18 - May 31, 2009. The highlights of the festival include interactive gardens, Disney topiaries and a concert series in the evenings. The landscaping throughout Epcot is absolutely gorgeous and definitely worth a visit! One of my favorite attractions is Minnie's Magnificent Butterfly Garden, which is a huge enclosure full of beautiful butterflies with exhibits that show how caterpillars build their cocoons and transform.
The second special event during your stay are
Star Wars Weekends at Hollywood Studios. The dates this event is happening during your stay are May 29-31, 2009. There are special shows, a motorcade, trivia contests and chances to meet your favorite Star Wars characters during the weekend. You can visit a special information desk at the park to get more information about that day's special events.
I have never personally used the pet kennels at Disney World, so I'm sorry that I can't offer any personal advice on that part of your question. However, I am happy to direct you to
www.allears.net where you can find some honest reviews from people who have used these services. Once you get to the website click on 'SEARCH' at the top of the page and type in 'Pet Kennels'. Click on the first result on the list. This page will give you some good and useful information about the kennels. Part way down the page you can click on 'Reader Reports' to read some reviews. I hope this information will be helpful!
