sells confirmed blocks of tickets that are defined as best available.

 This is an industry term that applies to tickets located in the orchestra (sometimes front mezzanine) sections of the theatre and that are sold at the box office at top price.

 When exact seat locations are not available for preview at the time of booking, best available tickets are guaranteed against allocation, and a confirmation containing exact seat assignments is e-mailed within one day of booking.

 Your group seats will always be together.( Sometimes larger groups like 10, the group would be split in two smaller groups like 5 and 5)
