Suggestions please

We have decided to get married next month, in a church where there will be me, my hubby to be, my two step daughters and other halves plus my grandson (aged 5). Afterwards, the seven of us are going out for a meal. We will have the big "do" we originally planned next May, but would really welcome some ideas to make this small wedding special, bearing in mind there are only 7 of us and I'm saving money for the big wedding in May. But I do want to make this day special. Thank you for reading xx
