Hi Jennifer,
The parks are beautiful at night, and fortunately, there are only a handful of attractions that close at dusk. Animal Kingdom has the most since the animals need their rest, but this park is not usually open late - except when there are extra magic evening hours. Kilimanjaro Safari, Pagani Forest Trail, Conservation Station and Maharajah Jungle Trek are the attractions that you'll want to see during daylight hours.
At Magic Kingdom, Tom Sawyer's Island closes at dusk.
Hollywood Studios has several live stage shows. Although, they don't close at dusk, there are only a specific number of shows each day. Make sure to check the daily park schedule so that you don't miss something you really want to see. You can also get an unofficial schedule by visiting Walt Disney World Entertainment. Click

Hope this helps. Have a magical vacation!
