Take a look at http://www.alykes.com lots of info about Alykanas and I'm sure someone on there will have info on Kalamaki.

I posted the latest review for the Alykanas village. We loved it but probably would have felt differently had ben been high season. Number of spaces for kids club seem to be around 40. Number of kids in high season 240, low season 24. Town very friendly, lots of reasonable eating places. Only real big downside to Zante is the airport which is a disgrace in this day and age. However its only for a couple of hours at the end. We would happily go back if we didn't have a firm rule never to go back anywhere. Lives too short, we did it once to Romania/Bulgaria and everything which was amusing, fun and an experience the first time just became a pain the second.
