We always rent a car and it's part of our
budget. When we have that size group we rent 2 cars. We are not always on the same schedule so 2 cars works for us. We like to go to the grocery store, Disney outlets, and even City Walk to eat, and the biggest plus for us is we like to eat at other resorts, and there's always the extra beer run if DH runs out. Without a rental car(s) getting to the other resorts to eat is very time consuming (90 minutes is the recommended time to allow for resort to resort transportation), but with a rental car is takes normally about 15 minutes. We also stay at the BCV or BWV for most of our trips and we don't have to drive to all of the parks, just MK and AK. We also like that we only allow 30 minutes to get to the airport while taking the bus requires a much bigger window. Changing resorts this next trip and having the rental will be much easier moving our luggage and ourselves to the second resort. And lastly, we are also Universal Studios passholders and if we feel the urge to go over to USF in the morning for a few hours we can do it easily. Our trip later this month is BWV week 1 and BLT week 2 and as always we will rent a car. There are many deals out there, so visit the transportation board. My daughter has a mid-size reserved for her week since she arrives on week 2 of our trip and she is paying $70 before taxes for a week rental ($120 after taxes) w/
Alamo. While alot of folks don't allow for rental car expenses, my savings is that I never pay to park when we go to WDW at our home airport saving us $10 day (x14 days this trip alone). Taking us an hour to the airport each way is a small price for our adult kids to pay for their use of our DVC points. Getting around Disney is very easy and getting there from the airport is easy also. Orlando does a good job with their signs.
