Since I only did snorkeling and freediving out of La Ventana (in 2022), I don't know what dive sites the La Ventana dive operators frequent. If I had to guess, they might go to La Reina's sea lion colony because San Rafaelito, as Chavodel8en mentioned, is a bit further, actually inside the mouth of La Paz Bay.I also read for los islotes that is closed for snorkeling with sea lions during the summer. That's why I had in mind to try swimming with the smaller colony -> Perhaps it would be less intimidating for a 7 years old kid?
I dove La Reina in 2019, and also snorkeled and freedived there in 2022. At least on those occasions, all I saw were adult sea lions and they pretty much kept to themselves, with the large male doing the rounds and barking every so often if people got too close. It is usually the juvelniles that are more playful, inquisitive and more prone to interact with people. Granted, this was in May so there shouldn't have been any juvemiles at that time.
Another place with good marine life in that general area is Cabo Pulmo. It is nonetheless abut 2 hours away from the airport and about 2 1/2 hrs from La Paz. But if you are also doing Loreto, adding Cabo Pulmo might be overextending yourselves a bit too much over a two week span. And in terms of lodging, you might find it comfortable but a bit spartan.
