We are heading down to Orlando at the end of October to do Disney, possibly Universal, etc. We are staying at the Marriott Harbour Lake and I'm wondering if we should rent a car. I'm saying yes but my significant other is saying no (she says we can just take cabs everywhere). Between driving to and from the airport and to/from the parks every day (maybe even twice a day on some days), I'm thinking that it will cost us way more if we just take cabs everywhere. I do realize that we'll have to pay for parking at the parks as well, but am I right in thinking that we should rent a car? There are going to be 4 adults and 3 children total so we'd need a minivan or something similar. The convenience of a car is attractive to me (no waiting for cabs), plus we'd likely go grocery shopping, out to dinner, etc.
