Travelodge is a nice economy motel, not too far from the parks on Harbor Blvd. They offer continental breakfast, & their snack room is next to the pool.
However, if you have the opportunity, I would recommend the Ramada Inn Maingate over Travelodge. It is comparable, however, the pool is bigger, they also offer a simple continental breakfast, and there is a food court there. Also, it is within walking distance to the parks. At the Travelodge, you'll need to take the ART shuttle ($3/day), or drive to the parks ($10 or $11/day parking), because it's a little too far to walk.
