I'm going to chime in here about how great this charity is.
My family is dealing with the illness of our child at this time; thankfully we live in the same city as the children's hospital, but there are many families that we meet that not so lucky. Ronald McDonald house has been amazing for them, providing them with food and lodging. Many parents have to take time off from work to be with the sick child, leaving them without a family income; having to pay for hotel and restaurants (especially for extended stays) in addition to their medical costs, would quickly sink the family.
On behalf of the families that we meet that have to make use of this charity, we thank you for your generosity.
