Did the Greece Tour in 2016.
Yes.....the toilet paper "protocol" is accurate. Just have to deal with it ....if you go.
No.....no shared bathrooms on our tour.
We did go to Meteora. We booked it through VisitMeteora.Travel. They have a separate website with TONS of information. There are several options. We opted to take the train to Meteora and spent one night. Delphi is coupled with Meteora on a few itineraries....we opted out of that since it was part of the tour. The VisitMeteora people were MOST friendly and helpful...although I am sure they got tired of my email questions :-)
We arrived several days before the tour started to do this. Took the train from Athens to Kalambaka/Meteora. Took about 4 hours. We did the first class option. The train was comfortable and clean. The train stations were a little worn. We got a Greek language lesson from one of the cleaning ladies on the train. She also got to practice her English...which she was very proud of. Her English was better than our Greek.
We had several hotel options. Ours was very nice....I think all of the options are very good.. Great breakfast. We did the "sunset tour" the first evening. It was not part of our tour package so it cost extra. The next morning we did the full tour. The guide was great. We were driven to the various monasteries via a nice mini-bus.
We took the train back to Athens that afternoon....only to be welcomed with a public transportation strike on our return....ugh!
I would HIGHLY recommend this company. It worked great for us.
One negative....for us....it rained the ENTIRE time. We were still able to visit the monasteries. Although my wish to get amazing landscape photographs did not quite happen. The scenery was still fantastic...or at least it looked great on the post cards. It was just bad luck. Yes....at the time it kind of dampened our experience, but as we now reflect back......no regrets even with the rain. Off the bucket list?.......but we kinda want to try it again on a sunny day.
ONE MORE TIP..........we packed a small day bag for the trip. Our main bags we left the at the hotel. The hotel stored them for us at no charge. We returned to the same hotel which was also the tour hotel. Worked great for us.
Hope this helps. And yes....too much for just one day.
I would HIGHLY recommend.
