Our travel plans changed slightly after purchasing theatre tickets and we now have an extra ticket for the night of our arrival. Is there a website or way to resell theatre tickets in London? Do people sell extra tickets outside the theater on the night of a show? Don’t want to breach ettiquite but also would like to get some of my money back for the unused ticket :)
Some theatres accept returns for re-sale.
See the section called "I cannot use my ticket" on TheatreMonkey: http://www.theatremonkey.com/whenitgoeswrong.htm
When is the date for your ticket? And what is the play? I have a friend who will be in London in August and another friend is going in November. They both love theatre.
Ticket is for Heathers the Musical on July 26-- so a little too early for your friends :)
