I guess it would depend where you are going.. (ps i was meant to go to Dh's cousin wedding in April too) wonder if it was the same one

Anyways A lot of places hire prams, car seats ect.. Esp if nearer to the bigger cities

Renting a car is possibly a good idea but I like the idea of a van but at the same time if you have your own car you can go off and do stuff on your own as well..
