I already own an old Porsche and I will drive it home.
I am very lucky. She has a good job and she will pay for any of her purchases herself. I can't care less what she buys except the house is getting full. She has not ever asked what I spend on my cars or this vacation. She will likely make a donation to the vacation fund for whatever she thinks it was worth. The hotel will be the same stupid expensive price with one or two occupants. Her meals are the biggest extra expense.
I am enjoying a nice Blue Moon Belgian-Style Wheat Ale beer brewed right here in Savannah. One of my traditions while on vacation is to drink some local beer. So far the Blue Moon and Yuengling Lager are keeping me hydrated.
