My husband and I went to see The Orchestra at Truro Hall For Cornwall, the venue is lovely, quite large though also small compared to some places in London, the sound system is excellent and the seating is arranged in such a way that EVERYONE gets a good view, there are great access and facilities for disabled and also Parents with babies and buggies. The staff are very friendly and helpful and you can join the Friends of Hall for Cornwall whilst there and benefit from exclusive tickets and also be the first to get booked so get great seats also alot of their shows offer you the chance to meet the cast or tour group backstage after if you opt for this membership, it also helps the enviroment and keeps the Theatre up to date and fantastic, give it a try.
