Childcare

I have 4 grandchildren I occasionally need childcare for at my Scottsdale Gold's. I pay an extra $10 a month for childcare, but have only used it twice in the past year. Last time I used it I was told there is a limit of 3 children, but since I had all four with me, they allowed it. My daughter, the children's mother, and I have used the childcare facility for several years, never with an extra charge. Apparently, the $10 fee just started last year. I need to take the kids tomorrow, and I don't want to embarrass them by being told only 3 can attend. BTW, the wonderful caregivers know all the kids and have known them for years.
