Seeing all of the press reports in the US over the winter, I worried that taking my family, including grown children of 18- 24 might not be a good idea. Isis, refugees, the Greek economy, ATMs out of cash, credit cards not working, pickpockets....all rumors that were a bit scary. I consulted with a few friends who had recently been in Greece and they said, "no problem, GO". We did, are in Greece now, and it is SPECTACULAR. Not the slightest threat to personal safety. Athens and the Peloponnese; no refugees, no problem. So you understand the dynamics of my comments below, I am 65 going on 49, my girlfriend is 50 going on 40, my kids are mature and well educated. We are active and fit; living in a ski resort in the Colorado mountains.
I can't think of a better time to be in Greece. First, the people are exceptionally friendly, helpful and 85% of the locals speak at least some English. Prices are off the chart low. It is still June which is the beginning of tourist season but Greece level 4 star Boutique Hotels run 40-125E with most being under 100E. High end dinners run 10-22E. The Parthenon had crowds created by tour buses but the rest of Athens was not tourist crowded. I was led to believe I would need a straight jacket to protect myself from pick pockets but I never felt threatened...not to say one should let down their guard, though. Nafplion was 25% of capacity so restaurants and hotels were easily accessed.
Greece is amazing. Very beautiful. Much to see. Lots of history...lots of today's vibe. The water is bluer than Blue. If you decide to come, make liberal use of the various on line booking websites for rooms. Most are offering discounts to attract visitors. Very little traffic on the highways once you get out of Athens. No issues whatsoever driving in Athens. If you can drive in Denver, you can drive in Athens.
If you are a "take a tour" type person, there are plenty to choose from. However, if you prefer to strike out on your own and just explore, you will have no issues. We had no advance reservations and made decisions on the fly, usually booking the next night's room on line the day before.
Had a positive experience at 999 Luxury Boutique Hotel in Nafplion. 4 star, $70E, very nice with very friendly staff. 1 1/2 hr massage for 45E....find that in New York City! Old Town Nafplion is not to be missed nor should your stay be less than 2-3 days. It is old Rome and old Athens on a more intimate scale. I could spend a month there. Great restaurants, very interesting shops, upscale clubs....no lines at all. Dancing and live music were a bit lacking but the classy bars were abundant. The castle was very interesting and reasonably well preserved.
The archeological sites that we saw were a bit over rated, particularly if you have toured Italy, where much is preserved. Much of the Greek sites are columns or foundations which leave a lot to your imagination. I suggest seeing a few but after a while, they kind of all look the same. You will visit the SITE but the buildings are truly ruins.
We headed out towards Lefkata today and drove the North coast of the Peloponnese. Do not miss the Corinth Canal...absolutely an engineering marvel particularly since it was built in the 1800s. You MUST stand on the bridge and look down. Not enough to drive over it on the Freeway.
Prices are even more reasonable in this area. We discovered a gem for the budget traveler who wants to have 4 star features. The Florida Blue Bay Resort in Psathopyrgos, Patra is directly on the beautiful Gulf of Corinth with a huge seaside swimming pool. All rooms have a sea view balcony, the dinner buffett was tasty for 10E, and happy hour was 2 for 1 on Mohitos, Pina Coltas and such from 9AM to 7PM. Double room on-line discounted to 40E.
Living in a tourist town, I travel a lot. Greece is a value like Mexico 40 years ago and the Greek people need our dollars to recover economically!
