Limo or rolls Royce

I think I personally would pick the rolls.

Having a moment with just your dad/parents would be - I think - a nice quiet moment together before the madness begins!
My sister had a kind of bus thing, like a Mercedes minibus with bench seats facing each other, so maybe that's an option if you don't need a luxury vehicle, but it's nice to have one! She had my parents and the bridesmaids in the car, and later it was the car used to ferry the bridal party to various locations for photos.

For our wedding, our ceremony and reception venue are the same place so once we arrive we don't need further transport, but maybe you do, and it's something for you to consider? We are also using ours as the getaway vehicle at the end of the night, so it's getting a bit of use!

I'd go for the Rolls Royce for a classy entrance. It might be a bit shorter on photo ops, but the elegance could make it a special memory.
