They recommend applying for no more than 3 internships, but I applied for more. They did ask me to rank them, though. If you apply to more than 3, they should probably all at least be in the same category so it doesn't look like you're desperate and will just do anything.
As far as transportation, it is a REQUIREMENT that you have a car. Taking a taxi every day would be expensive and a bus might not take you where you need to go -- plus you would have to be living near a bus stop. Disney transportation will only take you to the parks and resorts and you can't ride CP buses.
@ashleykay89 - I understand your frustration but trust me, internships are a great thing to have. You can explore different areas and work for companies that are on different levels. Even though working for Disney is great to have as a hospitality major, I have a friend who majored in hospitality, did the CP and continued to work in 3 different roles and still didn't get offered a PI.
