We had a white limo which took DH, his BIL (best man) and his brother to the church. It then picked up me, my dad, maid of honour and bridesmaids (dd, dsd, and dnieces) and took us to the church.
Me and DH went in the limo to the reception and my dad, dd, ds and dsd went in my parents car and bils and nieces went in bils car which sil drove to the church in.
The limo seated 8 people and my mum and sil had to get to the church so there was no point spending an extra £250 for a second car when it wasn't needed. If there hadn't been plenty of space in other cars going from church to reception we'd have either got a second car or hired a minibus or something.
