rob,
Just take your UK debit card, and draw what you need as and when required, let your UK bank know you are going or they may block your card.
The amount youll spend will vary depending if you are eating out etc.
Take a few levs with you to get you by for the first few days.
Cheers don, never like taking my card though as i often spend to much whereas if i take cash ive got a limit. also the fact that i might loose it as well
