Does anyone know why some websites ask for the number of 'seniors' as well as adults and children. I could understand if it was to ensure grandma and grandad didn't end up in an 18-30 club hotel but I very much doubt this is the reason, and I've never noticed them offering pensioners a discount. It can't be to do with selling their insurance, as if they offer that option it comes at the end, so do any of you in the trade know why they do it?
