Welcome to Disney Central!!! You will get lots of great advice on this site!!! I noticed you said you have 2 daughters. You need to eat breakfast at Cinderella's Royal Table in the castle at MK. The princesses will treat your girls like royalty.
A word of warning!!!:!: It is hard to get priority seating for this meal. Check out this site for some good advice.

This priority seating must be booked 90 days prior to your date. Since you said you are going in early May, you will need to book this in early February!!!! Plan now!!!!
