considering going to southern spain for the winter. but the long term planning has got us lost. what do you do about cash flow? if you pay by credit card how do you get the bill or do you take large sum. renewing prescriptions. utility bills in england i presume set up standing orders. can you get the red propane gas cannisters in spain? internet for the laptop and mobile phone is it signing up to a spainsh provider. is there anything else to consider? how far south do you need to go for mild weather?
