Can you suggest a good place for a 1 day family reunion in July in or around Red Deer Alberta?

I am looking for a nice spot for about 50 - 60 people - should have a park area for playing, an indoor facility in case of bad weather and where we can have a nice lunch. Also any suggestions for good caterers?Can you suggest a good place for a 1 day family reunion in July in or around Red Deer Alberta?
when we had our family reunion we used Burbank east of Blackfalds. Has campground and indoor facilities in case of rain. Another place is Content bridge by Stettler this is a campground as well. When we had our reunion we just did potluck and had lots of food.
