Looking desperately for beautiful place to holiday!

Hi.
I have a 18month old. And am pregnant with my second and in my first trimester.
We have decided to treat ourselves to a 10day break in May before this next baby comes. And for some reason I am finding it very hard to find a place to go to! Please can I seek some advice from you all.

We have discounted:
- Anywhere with malaria or that would require my son to get lots of vaccinations.
- Anywhere more than a 6/7hr flight

We are looking for:
- something like an all-inclusive. But perhaps one that isn't too big.
It's not traditionally the type of holiday we would go for, but the ease, the idea of no shopping/cooking is so very appealing.
- We don't want to put our son into any kind of childcare and he is too small for water slides etc so it doesn't need to be specifically a family place. Our son is very chilled and quiet so i'd feel comfortable taking him to a more adult-like place as long as they allowed children.
- somewhere that has a sandy beach, where the sea would be warm enough in mid May.
- with a pool
- has restaurants on site and if we wanted to stay all day there we easily could.
- somewhere that is near a pretty town where we could go to eat etc.
- ideally somewhere beautiful with a relaxed family vibe and if possible somewhere that has some character. I don;t think i could handle a generic hotel concrete block.

We are thinking of somewhere in Sicily, Sardina, Majorca, Turkey, Greece or Croatia...

Has anyone been to something that ticks these boxes please??
I would love some recommendations.

Thanking anyone who read through that..
