If your going to Kos forget travellers cheques, take some cash and your bank card to get money out the hole in the wall. Make sure you have access to a safety deposit at your hotel or find somewhere close to use, was burgled in Kos and two of us had travellers cheques, was told would have to go to Rhodes or Athens to get them replaced, none of this 24 hour service, talked about this recently in another post, anyway make sure somewhere safe to leave money and go the ATM halfway through your holiday, your going to Kardamena arent you?? I never went there but was in Kefalos and visited Kos Town a few times, been in total 3 times over 3 years. Any other questions fire away
