Hoildays for disabled with group support

Hi, can I just check, is it the carer/PA support to go on the holiday that you are looking for help with, or is it assistance when you are there (accessible facilities at the place yo are staying in that you require?   
i was at a conference day recently with a number of accessible holiday providers so I have some links there and I suspect there might be agencies in some areas that offer this kind of support, but I would have to look into that and other people on here probably have the experience of using these companies, which I do not.
