Wibly,
I'm heading down to phase 4 next week, 5th June from Aberdeen. I'm staying at a B&B in Totton which seems OK in terms of location-only £35 a night too (who says Aberdonians are tight?!). I'm not that fussed what the place is like tho-just want a bed for the night! The guy at the place reckons a taxi to CTC at Nursling from there is around £8, so not too bad. PM me if you want more details.
