There are several people who travel that far (and further) to the college everyday.
If you live in the Southampton area then why move...?
If you need to move to the area for the college then why not move to the area then that way you will be in the same boat as everyone else who has to move.
Some of the guys on the course i am on - travel and go out with us in town then drive home (or get a bed for the night with somebody on the course - not always the same bed as...you understand!!)
Hope that helps
Anything else feel free to pm
