Which Courtyard? There are several in the WDW area.
Generally, Courtyard's are pretty decent. Don't expect a fancy lobby or lots of amenities. The pools are basic - nothing fancy. However, the properties are generally well maintained and the rooms are clean.
We have stayed at the Courtyard in the Disney Village several times and we will stay there again. This one is nice because you get a larger room at a cheaper price (than WDW resorts), plus all the benefits of being on-site.
