Family compatible solutions for the Tauchgebiet with Hausriff?

Hello everyone,
in the hope for the Schwarmintelligenz: I have not found my/our request profile on the Forum and for which requests/recommendations very gratefully:

– Family with 3 children (8-15), all water rats, both are interested in water and were awarded a (Junior) Certificate in the Homeland for their water holiday
– Eltern Flachwassertaucher (Mexiko/Cozumel) with excellent experience, including AOWD and Nitrox-Brevets
– War tolls in Cozumel, even though the bootstraps were (zu) stressful, that is why we are now

* A Tauchgebiet, which is a Hausriff hat, soft drinks from Eltern (and which makes them both suitable for Kids) as well as Dive-Buddies from Steg/Strand with their own standard tauchen-können
* A (half way) empty dive shop at the hotel, with the man you can buy flask fillers, but not especially Tauchgänge or Ausbildungen buchen – or a local guide
* A hotel, with most children with swimming pool(s), beach and entertainment/playmates – and with the children of the Wunsch “Ferien in der Sonne” erfüllt
* Das Ganze has only made a financial contribution to 3 children

I had a look at the research on the Egyptians/Rotes More thought, aber das sieht Elternteil 2 critic (Kultur, Kriegs-/Krisengebiet). Is it a forum alternative or a better Vorschläge? I thank you very much!
