RSC and booking fees

I went this week to the Roundhouse to book tickets for the RSC's Histories in April and May.  There aren't many performances of each play, and it looks as though Henry V will soon be sold out and the others will follow.  The prices are reasonable with £30 the maximum, compared to nearly £50 for top Shakespeare in the West End.  By taking the tube up to Chalk Farm I managed to save myself around £20.  That's because online and telephone bookings at the Roundhouse attract a booking fee per ticket, a pernicious custom that really should be discouraged.  A small handling charge per transaction might be acceptable, but to add a per ticket booking fee is a disgrace.  Of course the Roundhouse is basically a music venue, and that's why they do it.  I saw the last RSC season at this venue, before it shut for rebuilding, and there's no question that it's a great theatrical space.  I wonder however how the RSC will cope with the acoustics.  Since the rebuilding I've been to the Roundhouse just once to see Tim Supple's Indian Midsummer Night's Dream, when the cast really strained to be heard.  The RSC's run in April and May seems to include a lot of blank days, so perhaps they realise the cast's vocal chords will be under stress.  The alternative would be to mike up, but that's not something that's accepted in straight theatre.  Having failed to make the journey round the M25 to Stratford for quite a while now, I'm looking forward to these performances a lot.  But I fear that anyone who doesn't book soon is going to be disappointed.
