just reread the op question.
boy did i screw up on this one......
you can get codes and get some deals for car rentals of sometimes $25 a day. if you do that, you pay the parking fee at the universal hotels of about $12 per night to park it there.
if you add those 2 numbers together, it comes to the cost of a shuttle.
i know sunray does a discount for more than one trip.
i paid them a total of $112 for a 3 leg run.
mco to grocery store, to wdw then to rph then back to mco.
if you don't have many in your group, use hte mears shuttle of $14 per person, it's a round trip cost.
or you could rent a car just for the day and return it in the evening so you don't have the parking fee at pbh.
if money is not a problem, i would use the towncar service. you don't have to deal with parking or traffic and would be picked up at a time you request.
how large is the group you will be with ?
all going to dtd together?
if you are using town car for returning to mco, check the prices of some of the car services. mco is closer to UO than it is to WDW.
