Beaulieu motor museum. If you gift aid you can return for 12 months. Small print says only the museum but we have still used all the grounds' monorail and the house as once in they don't ask to see an entrance ticket. The tours are great as they take you behind the barriers and we were touching all the f1 cars from the many years. Just sitting in the beautiful grounds with an ice cream on a hot day was lovely.

Jane Austin house in Alton. Although I enjoyed it I never felt there was enough there to return.

York Castle Museum - tickets are valid for one year - ID may be required on return visits. Not your typical museum, has something for everyone. The Sixties exhibition is pretty good

Not sure if they'll still be doing it, but the Tower of London offered 12 months free entry if you gift aided your ticket. Have to be a UK taxpayer to gift aid though.

If they're not doing it now, they may do it again sometime
