5 adults, 2 kiddos, staying off property, really close. Planning on taking our van down. Besides the parks, the only other activity I've heard mentioned is SeaWorld and I'm thinking we could drop off those who want to go to DW and the others could have the van for SW. Is it imperitive that we have a vehicle available for those not doing the parks? How much of a pain is it to drop off/pick up people who are going to the parks?
