Am going to Peru on 28th August, was wondering how much Peruvian currency to take - we have to buy some meals while there. Also is it easy to use credit/debit cards there? Or is it best to take UK or US cash to take to change?

Plus are there any other important things we need to now - e.g. about travel, sanitary conditions etc. - bit concerned about not being fit enough to cope with the climbing and altitude sicness

Would love to hear from anyone else going

Best wishes,

Alison
