As summer travel planning season kicks into gear, a Reddit discussion drawing 91 comments has aggregated the collective wisdom of experienced travelers into one essential lesson: the biggest mistakes aren't about what you pack—they're about how you plan.
"I've been planning trips recently and I feel like most people make the same mistakes," the poster wrote, listing the usual suspects: too many cities, no rest days, overpacking.
The responses confirmed these pain points—and added crucial details that could save first-timers hundreds of dollars and significant stress.
Mistake #1: The Checklist Trap
The most common error? Treating travel like a checklist rather than an experience.
"First-timers try to see everything," one commenter explained. "They'll do Paris, London, Rome, Barcelona, Amsterdam, Berlin in two weeks and come home exhausted, having seen nothing but the inside of trains and airport security lines."
Experienced travelers recommend the "less is more" approach: spend 3-4 days minimum per major city, allowing time to stumble upon unexpected neighborhoods, local restaurants, and the unplanned moments that become favorite memories.
Mistake #2: Underestimating Relocation Days
Moving between cities isn't sightseeing time—it's lost time. Checkout, transit, check-in, orientation. By the time you're settled, half the day is gone.
"People don't count travel days in their itinerary," a veteran backpacker noted. "If you're in 5 cities over 10 days, you've really only got 5-6 full days of actual exploring."
