Lastminute.com reviewer Robert adds, "Great weather at the end of October (19-29 October 2019). Full sun all days. Temperature 24-26'C and 22'C seawater.
The local Greek food is very tasty, and if you like there is plenty of international restaurants with Italian or European food too.
I explored Kos by using rented small economic car which is good enough for most places except mountain roads. There is everything you need on the island: history, beaches, food, nature, hot Spring, nice people and even you can do some activities like walk to the top of a mountain or spend time at windy beach learn kite surfing.
The roads are in good condition, just keep in mind that even at roundabouts car from your right side has priority (look at road signs).
Food prices aren't bad: for two adults and two children (4 & 6), you will pay about 35 euro (including drinks).
Kid's enjoyment: Beaches.
Adventure activities: Climbing."
