If you have to choose between cost and comfort, many will choose cost, but there are moments when you have to choose comfort over money. Public transport is a messy affair, and if you are a tourist, it's even more so. So, on your next vacation, forget about how much you'll have to spend on transport and how you can use that money for something else, and go for a car rental service. You are going to give thanks later, and if your kids are going to accompany you, they are going to appreciate the gesture. When you look back, you'd be glad that you were sensible enough to do so.
