We are two adults and one toddler and are hoping to get the van before October mid-term as wife is a teacher and we would like to get away in the van for that week!
With regards to the parking space size I created a thread on the forum last year with same concerns, end of the story was no problems as I rented one and it fit in the space without an issue.
