Ask anyone at YTB what its biggest challenges are right now, and one of the answers is likely to be "growth." That's a great problem to have and every department is literally bursting at the seams. Currently at about $7 trillion per year worldwide, the travel industry that YTB serves is thought to be the world's largest and fastest-growing business with even more growth on the horizon. YTB is experiencing its own reflection of this expansion trend. Upon moving to a new location last year, the management found almost immediately that it still needed more space, so it leased the top floor of another building across the street. Now that space is now officially standing room only, as well.
