McDonald's Hawaii is asking customers to round up their bills this week to support Ronald McDonald House Charities Hawaii, good news for families with sick children who need housing during treatment.

• Customers can round up transactions or drop spare change in donation boxes, with proceeds going directly to the charity.
• A portion of every Happy Meal sold also goes to the charity, along with money from community fundraisers and event sponsorships.
• Ronald McDonald House Charities Hawaii has housed families for nearly 40 years, giving them a place to stay, transportation, meals, and activities while their children get medical care.
• Customer donations added up to over $600,000 last year.

Outlook: McDonald's Hawaii hopes to match or beat last year's total through this week's round-up campaign.
