Create and fund a national holiday and respite grant scheme for disabled adults

I am a young adult, who is Deaf-Blind, Epileptic and I also have a serious neurological condition. To travel safely I need two support workers. I often pay for my own and my carer's travel and accommodation, therefore my one holiday can cost two or three times more than it would of a non-disabled person. I would like to be able to take short trips to Europe or maybe one further afield, but if staff changes are required mid-holiday, I also must cover the additional expense of those flights. Most charity help stops at 18 years old, so as a young adult there is almost no support.
