Have just been costing up a 3 night break in Seville for October, we haven't done a non-UK city break before, and I'm curious about how much people usually spend on a trip like this? Stupidly I thought it wouldn't be that expensive, but unless I'm missing something it will end up costing as much as a longer holiday! What tips and tricks am I missing, and what do you usually spend on this type of break?
