With a lot of objectivity and without any existence of Sonic and Sega, or their related levels, there is the results I found all over the Internet, all over the world:
Extract "Faliraki Rhodes Hotels Uncovere":
(Faliraki is a city near the bay of Kallithea in Rhodes, Greece)
"(...) the pool is of a average size next to a hill of dust and cactus with excellent views of the building sites. the bar was a hot and dusty little hut with a tv you couldnt watch as the owners sons sat all day with there hands on the remote. it is also VERY EXPENSIVE. A bag of crisps and a can of coke costing 3E 50C/£3. it also took 4 days and a complaint for us to get our linen changed and bin emptied. (yes the toilet bin) it not nice at all. there are also resident chickens living in the small garden. good alarm clocks if you get up at 6am.
