Christian Brother and Muslim Sister,Family reunions and prayer,what to do?

I have Christians, Muslims, and atheists in my family...we often don't join each other for prayer services at the mosque/church unless it's for a wedding or funeral, and we get together on both Eids (if it's possible to get time off) and Easter/Christmas.

During those holidays, the Muslim relatives go for Eid prayer and the Christian relatives go for holiday services on their own most of the time, unless someone wants to tag along. We all hang out the rest of the day.

Family and religion don't have to be the same thing.
