Back in November 2012, OC Register reported about a project in the City of Garden Grove that entailed the construction of a total of three hotels on a site located at the intersection of Harbor Blvd. and Twintree Ln. The project overall was supposed to include about 769 hotel rooms, 4-5 restaurants, and conference space along with 2 parking structures.

The tallest building (to the left), among the three, was to rise 19 stories with around 300-400 hotel rooms (Source: OC Register).
