Turkish delight
For a family of 5, Sueno Hotel in Antalya, Turkey is fantastic. It is an all-inclusive resort offering family rooms with the main suite housing the master bedroom and bathroom. A door connecting to the children's bedroom has no hall access so there's peace of mind that the little ones won't escape in the middle of the night. Just mind the sliding door from the children's bedroom to the balcony. The Hotel has an onsite kids' arcade and games room best suited for kids about 5 and up. There's also a a fair next to the hotel and for very reasonable ticket prices, kids of all ages can enjoy a roller coaster, Ferris wheel, bumper cars etc. And of course there is the beach - not white sands but more like Demerara sugar! I recommend splurging a little bit for a private cabana for the day. It comes with 3 refreshment breaks (including an ice cream treat) spaced throughout your rental period.
