I'm trying to figure out everything extra we'll pay with renting a car like tolls to/from MCO as well as savings (buying a few groceries on the way down for cheap breakfasts in the room). We're staying at Pop Century and we know that it would be easier for our family to have a car, but certainly cheaper to just use WDW transportation, so we're trying to figure out if it's worth adding it to our budget (currently I found a rate of $200 for the week for a midsize car that I think would fit our family tightly - we'll have luggage + stroller + carseats - one rearfacing). If we go through WDW transportation, we do have to buy a CARES harness for DD1, but other than that it's free, but of course there will be long waits at buses, full buses and possibility of standing with two little ones on the bus, waiting for DME and waiting for our luggage (not a big deal to us) and all that. What are your opinions? I guess what I'm trying to do is put a price on the convenience of renting a car versus the actual price of it.
