Good choice!
We'll pray for you.

Sounds fun!
Your travel day from Universal to Anaheim can be done quite easily via rail transit. You'd take the Red Line subway from Universal Studios/Studio City station to LA Union station, then transfer to a Metrolink commuter train or an Amtrak Surfliner (easier with luggage) for the 45 minutes down to Anaheim ARTIC. Then from ARTIC you could just do an Uber to your Anaheim hotel.
With a 10 minute transfer between trains at LA Union Station, it would take about one hour and 30 minutes and cost $15 to $20 per person, not including Uber cost. And it would certainly give you a fresh understanding of the vibrant and unique culture available to view inside the cars on the LA metro system!
*I'm trying to use that old LAX joke as much as possible now, because by 2025 that airport should actually be rather nice. It's impressive what $10 Billion can do for an old airport!
