Hey Shazy! Congratulations! Vacation Planner is a great role -- you'll love it. Basically, you get to be in air-conditioned splendor all day, selling a variety of ticket media and helping guests -- wait for it -- plan their vacations. Most VPs I know usually went to work fairly early, but they were usually home around 3:30, so that's a pretty good deal!
The training, from what I hear, is longer than most (though not as long as hotel front desk), so make sure you bring enough Disney Look business clothes as I don't think all of your training is costumed.
What's your arrival date, if you don't mind me asking?
