Hi Hashia,
This is a difficult question to answer as a lot of it really depends on personal preference. I bet that if you asked this question of each of the Moms Panelists, you would get a variety of answers.
Personally, my family have always found
Disney's Complimentary Resort Transportation to be super convenient, reliable and easy to use.
Although we generally have a rental care for at least 1 week during our 2 week stay, we rarely use it to drive to the Disney Theme Parks, Water Parks or Disney Springs. We tend to only use it for venturing off-site and to get to any Advance Dining Reservations we may have at Disney Resort hotels (other than the one we are staying at).
We prefer to take the hassle out of our visit by utilising Disney's Complimentary Resort Transportation which means that we can relax and just concentrate on having a great day.
Wishing you a magical trip filled with memories which will last a lifetime!
Emma
