Previous trips used GG, but with the delivery charge and tip, plus bell service tip we decided it was too much for what we really needed for 10 days for 2 people.
Last trip in Oct we used Uber for the first time ever, and were very pleased. It was less than $6 each way to go to the Publix in Celebration. We got to pick exactly what we wanted. Will definitely do this again.
Edited to add that was from the Boardwalk, less than $6 each way.
