Where to stay
Westby Road, Boscombe is the best place to stay by far, close to the college (max 10 minute drive even in rush hour) close to the beach and shops etc.
The best B&B is the Au Levant (I'm bias cos I've stayed there along time!). Its less than £100 per week and thats breakfast and a 3 course evening meal every night except saturdays!
I astayed in the Carlton Lodge, its nice but expensive and are reluctant to negotiate on price, no evening meals and no cooking facilities!
Some of the B&B try to get TATC's to sign mimimum contracts, pay large deposits or pay a month ahead, my advice is to avoid this and keep your options open. If you dont like the B&B you are staying in you should be free to move!
Westby Road seems to fill up very quick at the start of each new course, so book in one early!
