Hullo chaps

I got awarded my Respite money, but I do have to make a contribution. The only thing is that the money is sitting in my bank account, but I don't have any rules or regulations for it! I've been trying to get hold of someone to help me, but I'm quickly running out of time - we're meant to be going away on Friday but I can't get any straight answers about how I'm allowed to spend this money!
I don't yet have a debit card on the account (still waiting for the bank to pull their finger out), so what I wanted to do was to pay for my respite weekend out of my own account, keep a file of reciepts for my paper trail, and then transfer the money from my respite account when we get home, so that every single penny is accounted for. A friend of mine is on respite as well, and thinks I shouldn't have any problem so long as I really can account for every penny, but I wanted to get this confirmed by social services. My other problem is that I don't know whether or not I can claim for petrol expenses?

We're spending a long weekend at a friend's holiday home 250 miles away, so there's no accommodation costs, but there will be travel expenses, lots more driving around than I would normally do on a weekend, day trips and food for myself and my carer. I'm very confused about what I can and can't use this respite money for, and I'm so worried about doing something "wrong" and getting into trouble for it!
Are there any national guidelines about money for respite, or is it specific to each Local Authority?
