Feel free to ask questions about things in the South Bay area (San Pedro is considered part of the South Bay area of Los Angeles). I live 15 minutes away from the port & am pretty familiar with the stores, restaurants, etc. around the area.
If anyone has a few hours to kill, consider going to the Long Beach aquarium (Aquarium of the Pacific), we're members & my kids (8 & 3) love going to the aquarium.
