Best gigs I ever went to was with a good friend of mine who is paralysed from the waist down and in a wheelchair. Although he's totally independent, he gets to take someone along as a career and they go free. So we'd go halves in the price of his ticket. Priority entry. The views were always phenomenal, no danger of anyone bumping into you or standing in front of you, and usually no more than a few yards from a toilet.
