I've used minivans on many occasions and never had a problem with anything posted on here.
Seems people have "heard stories" and think every minivan is a death trap. They ain't.
I have seen big buses on their side, and even been in one when it had an accident, so there isn't any 100% safe way to go.
If the OP won't use a minivan and can't get a big bus, then the OP will either have to rent a car or a taxi or stay home.
