Hi Meenakshi!
I'm so happy to hear that you're planning to visit The Happiest Place On Earth during March break!
Ticket prices are based on age and 'options' you wish to include on your tickets. I can give you some 'rough' pricing but would suggest that you visit the
Tickets page of the site to get a true calculation of the prices for your family based on ages and the options you choose. You can even choose to purchase your tickets online before you go!
Based on current information as of today's date, a two day 'Base' ticket for a family of four with 2 children under age 9 is approx. $690.00. This ticket type allows a visit to one park per day. If you'd like to try to visit more than one park per day, you may wish to add the Park Hopper Option to your ticket, which would increase the price to approx. $925.00.
For your two day visit, I'd suggest you enjoy two parks for one day each, with the Base ticket.
Magic Kingdom is definitely a "must-see" with all the classic Disney attractions, parades, fireworks & characters. For your second day, it really depends on the ages & "favourites" of your children.
If you all love nature & animals, I'd highly recommend a visit to Disney's Animal Kingdom. It's such a beautiful park for the whole family to enjoy together. If your children love the Disney Junior Characters such as Little Einsteins & Jake the Neverland Pirate or are into Phineas & Ferb, Cars & Toy Story ... then Disney's Hollywood Studios might be the place for you to spend your second day.
If I can be of any further assistance to you in the planning of your days at Walt Disney World, I hope you'll visit me again Meenakshi. I'd be happy to give you further recommendations based on your childrens' ages and 'favourites.'
Wishing you a Magical time at Walt Disney World!
