Yes, I agree, knowing how to use Uber/Lyft is a MUST these days! I might resort to booking a private transfer so that they don't have to stress about transportation after 15-20 hrs in the air.
I did confirm with the TA that I can opt out of the flight package and reinstate it up to 90 days before sailing. This gives me a few weeks to consider any seat sales and also zero in on flights with decent connections. If I find something good, then I'll arrange flights myself and not have to deal with O.
