You've come to the right place for a great start! Here is what I would do in your situation:
1. Figure out which time of year you want to visit. This decision should be based on factors like weather, crowds, discount room rates, and, of course, your family's schedule. You might consider taking a look at this
calendar published by Disney. They offer some suggestion for great times to visit.
2. Next priority would be deciding upon a place to rest your head at night. There are many
benefits of staying in a Disney resort including: free round-trip airport transfers, extra magic hours, and the availability of the dining plan (more on this later). Disney offers accommodations that range in both price and theming with something for every guest and just about every budget.
3. You'll want to consider where you'll eat on vacation too! You may want to take advantage of a dining plan. Disney offers several options for guests including a
counter service dining plan all the way up to the deluxe plan. Once you've decided that, remember to call for your table service dining reservations at 407-WDW-DINE.
