It is an amazing experience-but don't underestimate how tiring it will be. I was exhausted the whole time. YOu will room with someone you've never met-and end up staying up all night talking to them like you've known eachother forever (unless they changed that for the dorms). I ended up sleeping during every break we got!!!
Star Turtle--surely you have a sister who can loan you a formal! It doesn't have to be pageant quality...just something classy & nice. Bring as much cash as you can for the jewelry (you will want a convention dangle), etc. Are they doing the breakfast where you wear the dog ears still? That was fun. You will probably get a canvas tote bag to carry things around (I still have mine). If you can't call your CCD, feel free to contact your RCD or HQ...maybe there's more info on HQ's website?
