A trend in some cities is to help finance new sports stadiums and other initiatives by tacking on a surcharge. An extra fee is usually charged if a car is returned to a different location than where it was picked up. This fee varies on location so there usually is no general policy regarding this. Rates are based in part on how many cars the agency has available at your pick up location. Be responsible and cancel your reservation if you have a change of plans.
Most car companies offer child safety, toddler and infant seats.
Since there may be limited availability for these you should reserve these well in advance. Be aware that at some locations, you can only request a child seat to be their waiting for you without a guarantee. Many companies currently are offering online discounts on the internet. When reserving online, be sure to print out or take note of your confirmation information and take this with you to the counter. To get the best service, check your rental car companies website or inquire with them for what exactly they offer in the way of special services.
