Hello Melanie!
Thanks so much for visiting the Disney Parks Moms Panel with your question! I'm a big fan of the
Disney Dining Plans! They're such a great way to sample some of the fantastic dining options at Walt Disney World, so I think you've made a great choice for your vacation.
For the Disney Dining Plan you'll be using, each person in your travel party will receive entitlements for 1 table-service meal, 1 quick-service meal and 1 snack per night of your stay, so for your visit dates, that totals 5 of each per person. You'll receive all those entitlements when you check in and you can use them any way you'd like up until midnight on the date you check out (April 17, 2015). Making reservations for those table-service meals can be done up to 180 days in advance and I'd strongly recommend doing that to be sure you're booked at the restaurants where you want to dine. Also, be sure to check your account before you check out to see if you have any entitlements available! My family usually has some snack credits left over on our last day, so we like to grab a few things for the plane ride home or have one last Mickey ice cream bar before we say, "See ya real soon!" to Walt Disney World.
Wishing you a most magical vacation, Melanie! Please let us know if you have any other questions as you make your plans.
