Business trips can be pretty stressful if there is no real downtime. If you are all simply working your fingers to the bone and then passing out after a long day, there is no real time to decompress. If your team is not going on business trips and there just needs to be a place to hang out at the end of the day, happy hour is great for that as well. Local bars usually offer great drinks at great prices. They also may offer discounted appetizers and specials on meals.
