There is a limited amount of Disney-provided housing at Cumberland Apartments. Just like in the cp, furniture and utilities are provided and you have to share a room with another person. There are 2 and 3 bedroom apartments and I believe the price difference is like $135/2 bedroom per week and $128/3 bedroom per week.
However unlike the college program, not everyone stays in Disney housing and there are plenty of apartments in the Orlando area available. In my opinion, the nicest thing about staying in Disney housing over somewhere else is that you are living with other people doing the program and your lease begins and ends with your program so you're not stuck paying for extra months. If you're interested in living in Orlando after your internship, finding other housing might be a good option for you.
