DQ Welcome Building

I wanted to book tickets for 3 people for 3 separate shows I am an electric wheelchair user, live alone and drive. However I cannot go to the theatre in Eastbourne with my sister and disabled brother in law who uses walking sticks as they would have to sit Infront of me to sit together as only one seat next to wheelchair user and also my sister as the able companion was not allowed. to be responsible for 2 people so either had to sit with me and my brother in law sit alone or I can't go ! We are regular thetre goers and have been to London and many other places and always have been helped to enjoy our visit so it is a shame that so close to home I could not get past the box office
