I don't travel a ton, but usually when I do it's for a week or two at a time and often internationally. I hate being gone for 2 weeks. Really sucks, and I don't even have kids. Certainly don't mind travelling mid-week within the US to a decent place (or even a new place, even BFE Montana). Also like those opportunities to go places and see things I never would have on my own (like in 2012 got to do a week in Israel and check out both Tel Aviv and Jerusalem). But I also had to do Miami like 5 weeks in a row. That got old quick, even eating and partying in South Beach almost every night.
I like doing two weeks internationally because you are almost always assured of at least one day to explre.
I know a guy who used to go to China from California and was in China for one day. ugh
When we go we're guaranteed the weekend, for sure. But like here's what I'm talking about:
Sunday, Day 1: Fly MCI to Frankfurt, Frankfurt to Copenhagen, get to hotel early Monday morning
Monday, Day 2: Nap, wake up and walk around Copenhagen for dinner, try to get some sleep
Tuesday, Day 3 through Thursday, Day 5: work hard, pretty much no personal time, but nice dinners out every night
Friday, Day 6: Fly Copenhagen to Frankfurt, Frankfurt to Tel Aviv, afternoon and evening free in Tel Aviv
Saturday, Day 7: Free day, travel to Jerusalem an tour around, stay the night in Jersalem
Sunday, Day 8: Free day, go to Dead Sea, climb Masada, head back to Tel Aviv that night
Monday, Day 9 through Thursday, Day 12: work hard, no personal time, dinners out every night
Friday, Day 10: Fly Tel Aviv back to MCI (not direct of course LOL)
Yes, it's fun, but I just hate being away from the things I love and care about much more than work for two weeks. Also hate giving up a Sunday to travel for work. But like I literally got to touch the ground where Jesus ascended to heaven (the second time, I think, allegedly).
