group tours in southeast asia: visa headaches and onward tickets

We’re getting ready for this big G Adventures trip through Thailand, Cambodia, and Vietnam, and I’m honestly a bit stuck on what to do about onward tickets. After Hanoi, I have no clue where I’ll end up—maybe Laos, maybe back to southern Thailand, or maybe I’ll just throw caution to the wind and fly to Sri Lanka. The problem is, I don’t want to lock myself into a flight just yet. But I keep hearing that when you cross into Vietnam by land, they might hassle you if you don’t have proof of onward travel. Has anyone actually been grilled at the border for this? I’m not exactly keen on getting stuck in a sticky situation, especially after all the planning we’ve done. And then there’s the whole visa mess. I’m a British citizen, so technically I get 45 days visa-free in Vietnam, but should I still bother with an evisa just to be safe? And what about Cambodia—should I sort out the evisa before we leave, or is it really as easy as everyone says to just get the visa on arrival at the border? I’d hate to be the one holding up the group because of paperwork. Honestly, all these rules make me miss the days when you could just show up and figure it out as you go. Anyone else feel like the red tape is half the adventure (and half the headache)? #southeastasia #grouptravel #visaproblems #Travel
