I am comparing a car rental with Tiffany Town Cars and I can't justify renting. The taxes alone are either $43 (offsite car rental) or $59 for a rental company at the terminal. This is for a one week rental. Add on gas, and tolls and its a lot of money, even for a cheapo rental rate. We don't HAVE to have a car - we're staying onsite. I like having car, because I'm a control freak, and I like the option of driving. However, I'm having a hard time justifying the cost for this trip!
