The Walgreens and Target are in the same plaza on the corner of Chapman and S. Harbor. It is about a $12 taxi ride when we did that 2 years ago from GCH to the Hyatt hotel which is on the adjacent corner of Chapman and S. Harbor. Maybe you can take the ART? As the previous poster said, it is not walking distance. The GCH has a sundries shop that sells some medications, but definitely limited in its offering.
