We took an Uber & Lyft, check costs & compare each about $20 there, more expensive back in some cases.
Rental compact can be had for 240 a week (or less). But parking costs are high. Parking at WorldMark is included in your stay.
we used Uber, it was the cheapest and most convenient for us. it also allowed us to come and go whenever we wanted. there is only one shuttle service from worldmark, but it is not a dedicated pick up. you have to call in and the times are limited. plus, very expensive per person. we used the mears shuttle to/from to airport. however, we learned the car rental prices in Orlando are very low...but then you have to deal with parking lots and fees! depending on the size of your group, you may consider a rental.
