There are only 3 resort dinner character meals, 1900 Park Faire at the Grand Floridian, Chef Mickey's at the Contemporary and the Garden Grove at the Swan (although the character interaction is limited to Goofy and Pluto) 1900 PF has Cinderella, Prince Charming & their friends and family while Chef Mickey's has Mickey, Minnie and friends. Do you know how your 4-year old feels about costumed characters? You may want to choose the "face" characters at 1900 PF is she is afraid. I prefer Chef Mickey's.
You may also want to consider paying for an extra day so you can go into a park on that day. It's usually only about $10 per person to add an extra day to your park passes. In the parks you can visit Pooh and friends in the MK, Princesses in Epcot and the Disney Junior characters at Hollywood Studios.
