i do the same.
i split my trip from disney on site to hrh at universal each year.
(some years i do rph or pbh instead)
since you have 5 people in your group to relocate, you would be better off using car service.
i would recommend a couple but dis no longer supports them and their name would be starred out.
it would be $50 for a one way trip.
i took a taxi before and there were 2 of us.
from disney to hrh it was $36 plus tip for that time.
taxis charge by person, mileage and time.
if you would travel in rush hour, it would cost more as of the time it would take for you sitting in traffic.
do car service. they will accomidate up to 5 without extra charge.
