I have also heard that the Pelin is exceptional value as they mainly cater for short stay tour parties, so you may struggle for 8. Also
nearby is the Rebin Beach Hotel, I have stayed their the last two years and have booked again for this year. Inexpensive, good Turkish food with anm excellent Pool but no lifeguard so you cant leave the kids unattended. Both the Pelin and the Rebin Beach require a trip over the Dual Carriageway to get to the Beach, Bars and restaurants but it is not that busy. Both Hoetls are on Travel Republic and I beleive
www.sunshine.co.uk, check the Holiday prices but if you are flying from Manchester worth looking to msee if you save with EasyJet booked direct and Hotel through the above.
Calis is quieter than Hisaronu / Ovacik but close to the Beach.
Search the site here for a thread entitled Calis/Fethiye 1st Timers you must do this -- you will find it extremely helpful!
Enjoy!
