I never really saw the point of PPI after reading the small print but we had a Barclays options (?) current account - one phone call from Mrs P to Barclays resulted in a £2200 payment. I was sceptical after one of her friends suggested it but that really was all it took.
So two separate weeks? Not an issue really. The first time I did London I didnt even get a place until february, a rest over christmas and another in feb will do no harm at all if you start training now.
