Can Anyone Help...?

I'm seriously considering travelling to the UK this year to see John Barrowman live in concert. I'm looking at going to the Cardiff concert on November 13, and structuring a holiday around that - a couple of weeks in London, approximately a week in Cardiff, and then back to London for a few days. Approximately 20-22 days in total.

I've worked out that I need around $2800AUD for flights and accommodation, leaving me with the equivalent of around 4,000 pounds for everyday spending and extraneous transport.

My question is, could I comfortably survive with around 200 pounds spending money per day (including the cost of food, every day transport, and any souvenirs I might like to buy)? Or am I being over-eager?

I really want to do this trip, because I have a nasty feeling that JB probably won't have a concert tour next year because of the Olympics, and I don't want to miss this opportunity, if I can manage it. Any and all help in figuring this out would be immensely appreciated. And in return, I promise to post the next chapter of my latest "What Never Should Be" installment this coming weekend...

OH. MY. GOD.

I'm going to the UK in November!!! Put in my leave application, and my manager signed off on it straight away! I am now in the process of booking my flights, and accommodation, and on the weekend I'll be booking tickets to JB's concerts at the London Palladium and Cardiff!

It's 4.30pm and I am just about ready to bounce straight out of my chair. I'm coming to London to see John sing!!!!!
