Depending on which session you go for, eg AM or PM i would suggest staying as close to Fareham etc... as possible. I personally wouldn't want a long journey by public transport in this country when i have to be at a certain place by a certain time.
Can you not fly directly into Southampton ??? to make your journey this end easier ???
I personally live in fareham and let me know if you need anything regarding B&B nearer the time, there are a few in the centre of town and a taxi ride will be about £10 and take 15 mins or so to CTC at whiteley.
