Hey Gavlos!
Have you planned your trips yet? We've done a few really good ones!
The Grand Island Tour is fantastic- did it a few years ago but I'm booking it for my mum and dad's birthdays this year as I know they will love it too.
Theo's Boat Trip is awesome for the kids - it's like a family friendly party boat, takes you over to the Greek mainland for an amazing BBQ on the beach with watersports etc. You then get to jump off the boat at a lagoon. The boat journey is about 1.5 hours there and same back but it's a party atmosphere!! Theo and Harris (his son) are what makes this trip so special but you have to book it through Thomsons. You can book direct but it ends up costing more for your own transfers.
Paxos and Anti Paxos were fab.
Corfu town by boat in the evening was great.
Hire your own boat from Noula and go round to Paleokastritsa or some of the smaller beaches.
Water Park is good - I didn't but then men and kids in our party did and loved it.
