Hi,Has anyone used viator to pre book broadway show tickets?The company e-mails vouchers,does this work well?Also are the seats as good as they claim "Seating is assigned by the theatre's box office on the day of performance, and will always be top price locations in the Orchestra or Front Mezzanine section ".Quoted £150 for 3 to Mama Mia,is this a good price?

Thanks in advance
