Which of the following Disney Resort Hotels are located within walking distance or a short boat ride to Disney's Hollywood Studios?

Disney's Beach Club Villas is indeed the correct choice because it is situated close to Disney's Hollywood Studios, making it possible for guests to either walk or take a short boat ride to the park. This proximity not only offers convenience for visitors looking to maximize their time at the park but also allows for a scenic stroll or relaxing boat ride along the waterways of the resort area.

The other options represent resorts that are not within such convenient distance from Disney's Hollywood Studios. Disney's All-Star Music Resort is located further away and requires transportation via shuttle buses. Similarly, Disney's Port Orleans Resort is located in a different area of Walt Disney World and does not offer direct access to Hollywood Studios by walking or a short boat ride. Disney's Art of Animation Resort is also positioned at a considerable distance and does not have the direct waterway access that would facilitate an easy journey to Hollywood Studios.
