Omni makes sleeping away from home fun for kids. Room service will deliver milk and cookies to your kid on the first night of your stay, and some Omni locations offer Kid's Fantasy Suites (the one shown here is in San Francisco), a separate room with bunk beds, toys, and even a TV.
Upon check-in, the Omni Sensational Kids provides each child with a backpack filled with fun items including a discovery map with 32 games, crayons, a Hacky Sack, and Twizzlers. You can also hit up the front desk to borrow a suitcase filled with games and toys.
