You will LOVE CTI!!! Relax and have fun! Don't overplan and no worries! One thing you should do is take the resort orientation when you arrive. It's offered every day at 10am and 5pm and is a great way to get to know the resort. It's a tour led by a member of the entertainment staff so it's not only informative, but it's fun.
Have a great trip! We've been to CTI many times (it's our favorite!) so if you haev any specific questions don't hesitate to ask (firstname.lastname@example.org).
Oh my gosh, you will LOVE LOVE LOVE CTI. It is the most wonderful resort in the world IMHO. We are going back for our fifth time in January, and everytime is as wonderful as the first time. There is so much to do at CTI, that you will be amazed. Plus it is all included. You will have the best time of your lives from the minute you step off the bus, to the moment they are dragging you back on. Happy Travels
