You can stay overnight when seeing a show at Malvern Theatres with their theatre break scheme. Special rates are available at The Cottage in the Wood Hotel.
The theatre is also discounting cinema tickets by £1 and so long as you are able to produce the Door Drop voucher recently delivered to your home in Malvern or if go to The best of malvern "Offers" page, you can print the voucher off and take advantage of a discount on your evening out.
