The location of the Dolphin Centre and convenient parking can be seen in the map below.

 

There is a large multi-storey car park very close to the Dolphin Centre.  Drive up Beaumont Street and turn right through the automatic gates, taking a ticket as you do so.  The ticket allows you back into the car park so take it with you to the recital!  The charge is free for the first two hours but is £2 for a longer stay - which is highly likely given the length of most recitals.

 

When leaving the car park follow the exit signs which may be uphill - the exit is on Level 3.
