This is something we at Carlson Wagonlit Travel have been paying attention to for a couple of years now. One of the interesting things we see is that people might tack on leisure travel to a foreign trip or even to a trip two states away. People see travel as exotic, but exotic is different for everyone. And younger travelers are definitely more likely to travel this way.
Your company may not have a travel policy to cover this, so make sure you keep your expenses clearly separate. You may actually save your company money by adding a Saturday night stayover to your trip, and it would be hard for your company to have a problem with that. However, when you stay those extra nights, it’s probably best to change hotels, to make your expense report easier to file. (And you can probably find a hotel that’s closer to tourist spots, rather than one closer to your meetings.)
In the media
Companies may want to consider looking into making this a formal part of their travel policy. Depending on the industry, companies want to provide for their travelers, and create an environment for employee retention and have a high quality employee experience. Some companies are even promoting their travel policies as a way to attract employees, and that trend has grown in recent years.
There’s no single solution that will work for every company. The one trend that is universal, though, is that younger generations moving into business travel like the idea of blending business trips with personal trips.
