This looks perfect for my father now in his 70s (3d generation Irish American). I suspect some of my siblings would want to come too. How many people can we have in "small group"?
Vagabond (adventure) and Driftwood (sightseeing) vans have 13 passenger seats. We had 12 people in our group and so we had a spare seat. Your luggage travels in a trailer behind the van so, even with a small day pack inside the van, it's quite comfortable.
The van used to transport passengers only seats 13. That's the max for now.
