As the event is in term time we cannot offer accommodation in University of Southampton halls of residence (for that genuine ‘trip down memory lane’ experience…).
The link below provides information about different types of accommodation in Southampton:

I would mention that the Elizabeth House Hotel (http://www.elizabethhousehotel.com/) and the Highfield House Hotel (http://www.highfieldhousehotel.co.uk/) are both well located for the Avenue campus and the Highfield campus, although I should stress I have stayed at neither (I have heard, on good authority, that the Elizabeth House Hotel does a mean full English breakfast 🙂 ).
