Hi Alycia!
Packages/discounts have not yet been announced for next April. Typically discounts are announced only a few months in advance. My favorite place to check out discounts for anything Disney is
mousesavers.com. Disney also has their own page for
special offers that is updated when new offers are announced.
When our children were young, our favorite time to visit was early November. The weather was always beautiful, no rain, little humidity and manageable crowds. With your children being so young, you may not have to worry about school schedules. If you are considering going in April, I would try not to go during the school's April vacation week as the parks can get quite crowded.
Without knowing your budget, it's hard to determine what resorts would be best for your family. Disney has many resorts for all budgets - value, moderate, deluxe and vacation villas. You may want to check out the
resorts section on disneyworld.com and also consider ordering the
free vacation planning DVD. You'll get an idea on what resorts Disney has to offer.
I hope this helps get you started! Please write back with any follow-up questions! Diane :)
