My husband and I heading to Crete, Santorini, and Mykonos (3 nights each) at the end of September. He has never traveled abroad and is concerned about travel distances. I plan to rent a car while on Crete, and I've read it is a good idea on Santorini (hotel is in Pyrgos) to get to outlying spots. What about Mykonos? We are more in-town there, but will be going to Delos one day. Does the convenience outweigh the cost and locating parking spots?
Crete is huge and you'll definitely need a car if you plan to do any long-range exploring. If I were staying in Pyrgos I'd want some sort of transportation to move around the island at my own pace but it's not a necessity like it is on Crete because Santorini is small and has an excellent bus system. Taxis are also available. Mykonos is small and has an excellent bus system as well.
If you live outside the UK or the Schengen Zone don't forget to bring an International Driving Permit with you. If you live in the US or Canada you can get them at your local AAA/CAA office, no test or membership required. Bring 2 passport photos with you to save a few dollars.
Thanks so much for the input. We have our driving permits, and since we are AAA members, they took the pics there for free.
