I'm a programmer and my wife is a real estate agent. We only travel about 4 or 5 full weeks a year. I can work almost from anywhere as long as I have an internet connection and phone. My wife can coordinate members of her team when we're traveling and can almost work full deals. I don't particularly like working while on vacation but we are very thankful for the fact that our jobs allow us to travel at least some. I guess my job actually could allow full time but that's not something we have interest in pursuing.
