Please, please, please do not promise your daughter anything as far as Toy Story or Dalmatians. Rooms are ASSIGNED 5 DAYS OR LESS than when you arrive. Requests for a specific theme/building, be it All-Stars, Pop, or any of the other resorts on property, are just REQUESTS.
Although if you go in Feb. during group season, you'll probally get Toy Story, 101, or Fantasia, because Mighty Ducks and Love Bug are used as group buildings.
Now that I probally brought you down, here are some pointers about how to make it great!
Fax or call resorts specifically with requests about 5-7 days before arrival.
State that you would like to be in certain _______ when you arrive. Don't make a huge fuss about it though. 95% of CMs will try and accomodate your wishes. It just might not be possible.
If staying for more than 1 or 2 nights, don't be afraid to ask about changing rooms if something becomes available at a later date. Luggage can be moved for you (if packed like CMs ask) to the new room.
Try to arrive as early as possible (after 7 am). The earlier you are, the better chance of getting what you want because people haven't filled all the rooms yet. Don't expect to get exactly what you want like FL residents do on Friday/Saturday nights if you arrive later in the evening (although Feb isn't bad except for weekends and President's Day).
