There are SO MANY Disney blogs and information websites out there, that sometimes it can get really overwhelming. I like to show different resources that are out there, and I've found one that can make your planning a lot easier!
YourFirstVisit.Net is a great site that helps you navigate your first time at Walt Disney World. However, even Disney veterans can use a handy new tool, the Week Picker! You answer a few simple questions (based on crowds, weather, and money preferences), and then your best weeks are given to you! There are three tiers - Deluxe, Moderate, and Value, since prices can vary by different hotels.
Our next Disney trip will be in late 2012 or early 2013, so even though I have awhile, it always makes it easier to make a gameplan of when you're thinking of going. For instance, I always make my dining reservations 6 months out, and this helps me to know that I'll need to make reservations next summer, probably in August (exactly a year from now!) if we go in January.
This is a handy tool that can help take the guesswork out of when to visit the World!
