Of course! Children are welcome at the festivities, but we want all the parents to be able to enjoy themselves at the wedding itself (and weekend away) so we've been recommended https://www.cabobabysitters.com/ as the best in the Baja. We also provided a few hotel options, some being more family friendly than others.
Taxi shuttles are available. Uber is available in Cabo and to the airport, but unfortunately they cannot pick up from the airport yet. Pro Tip: They'll charge you about $50 USD at the Los Cabos Domestic Terminal vs. $80 USD from the International Terminal so you can negotiate
We use Uber now that it's available or the taxi vans for bigger groups.
