Create A Group Fund
When you’re traveling with more than a couple of people, splitting the bill every time can become a headache. Put together a group fund for all of the agreed upon expenses on the trip like guided tours and restaurant meals. Then put one person in charge of paying group bills when you get there.
They’ll keep track of the expenses, and if anyone consistently spends more (on upgrades, perks or drinks), agree ahead of time that they’ll put more in the pot to compensate when the time comes.
