Activity for Amy

The back of our invitation says: “camping is available, and free, for those that wish to stay”. I need help with grammar. Are the commas in the correct places?

Looking for advice. My fiancé and I are paying for most of the wedding ourselves but our parents are each pitching in about $1,000 each (which we are SO greatful for!). Do I still list “together with their families” on the invite or leave that...
