Αίγινα??

AíginaもしくはAegina island'sなのではないのでしょうか？でも、”エガテ”とは似てもいないし・・・。

How to get to Aegina island

Only 40 minutes from Piraeus
The airport of Athens is the closest airport to Piraeus from where the boats leave to Aegina island. Bus X96 will take you between 60 and 90 minutes from the airport to the Piraeus port. Aegina is located at only a 40 minute Flying Dolphin distance from Piraeus. The regular ferry takes around 75 minutes.

Do I have to buy a boat ticket in advance?

When you want to be 100% sure of your ticket, it’s recommended to buy your ferry ticket in advance. Especially when you need to catch the last ferry or a plane.

>ギリシャの島嶼部ではwifi　繋がりにくいと聞いていますが、シムカード入れ替えて行った方が

無線LANは人が集まる場所（空港、ホテル）でしか繋がりません。それが仕様です。海の上や海岸で電波が捉えられる可能性は、船以外ではあり得ないでしょう。国内で売られている民生用の無線LANルーターが障害物のないところで100メートルと言われていて、障害物があれな数十メートルです。人の居ない場所で繋がるとは考えにくいのです

Internet Access

Free wi-fi is available in most hotels, many cafes and some restaurants. A number of cities have free wi-fi zones in shopping and eating areas and plazas. Internet cafes have virtually disappeared – instead buy a local SIM with data to insert in your unlocked device. Some, but not all, hotels offer computers for guests to use.
