A friend of mine was struggling recently when trying to find the right car for his trip to Chaumont. His companions included his grandad who needs a wheelchair to get around. He was looking for a big vehicle that would allow his grandad easy access as well as a good amount of space for his chair and other essentials.
Most of the usual car rental websites were coming up short until he found a specialist 9 seater website at https://www.9seatercarhire.org.uk/. This was great as it only lists nine seaters. It made making a decision so much easier.
If you are in a similar situation then they are worth checking out. Minibuses and MPVs as well as People Carriers are often the names used for such vehicles so keep that in mind when searching.
