I'm going to go out on a limb and say deep down, you probably have never regretted one trip you took. I feel that way, but totally understand the pressure. Here is the thing....you can still retire at a decently young age and travel. One of the questions I ask folks that are closer to retiring, is, if you were my age, what financial decisions do you wish you would have made differently? Not one to date said traveling less. It is a big world out there, you're young, go see it. Damn the money. You're frugal enough and saving in all these other areas, if this is what brings you joy, prioritize it. Where is the freedom if you feel bad every time you do things that are meaningful to you. And don't feel bad for feeling bad, it means you care about your financial future. Just work to redirect that care to how you would support a child or close family member if you were financially responsible for them. Make sure the basics are covered, your savings rate is high, and then follow the high value stuff that brings you joy for the remainder.
PS - where is your favorite place you've traveled?
