Safeco Field is a great experience for families. Kids will enjoy the game, the activities on the main screen, and the M's do a good job of making everyone feel welcome. Some tips, if this is your kid's first visit to Safeco Field, you can visit one of the Information Centers inside the park and get a free certificate, value menus at the 105 and 319 concession areas, and there are tons of giveaways throughout the year.
