 During retirement, travel expenses can vary significantly depending on where you go, when you go, and also how you go. If you're bringing along kids and grandkids or you're staying at a higher-end resort, you're clearly going to spend much more than you would if you were staying at a Holiday Inn Express off the interstate. It may also be beneficial to travel more often earlier in retirement because as you get older, you may not want to hit the road as much and because you may need more money to address your health care needs.
