Holiday (2separate bedroom) advice

[Tricky28]

I am looking for a holiday preferably in Greece somewhere by a beach - we have always done a TUI All inclusive holiday - but as our 2 kids are older we would like to book a hotel which has a room with two bedrooms so the kids are not sleeping in same area as us !! (Interconnecting rooms seem not to be an option as they cannot be guaranteed and don’t want one adult and one child in each room miles away from each other ?? Anyone got anywhere they recommend ??
Also been looking at Vrbo to hire an apartment and book flights separately etc but very scared to do this as always had a package hol ?? (Also don’t want to hire a car!) Can you give us some confidence to do this as some apartments look great and would be more comfortable for older kids and us ??? Thank you
