Holiday accommodation for extended family

I’m looking for ideas for a holiday for the extended family. in the past few years we have been going on canal boats and then adapted canal boats because I am now in a wheelchair but there don’t send to be many places doing adapted canal boats left… so we are looking for somewhere for 8 adults which is wheelchair accessible with a disabled bathroom for me, my sister in law is keen to try out their Land Rover with a tent on top combination, my son and his girlfriend have a camper van so in reality we might be looking at a holiday park that does disabled cabins plus you can camp. there. We. aren’t too bothered about staying in the same type. of accommodation so long as we are near together and there is somewhere we can all sit in the evening to play noisy games. Any ideas please?
