Anyone else struggle with small daily travel costs adding up?

Just got back from a 10-day trip where I thought I was being smart with money.

No big tours, no fancy restaurants, didn’t buy anything I didn’t need.

Still somehow blew through most of my budget by like day 6.

And it wasn’t even anything cool — just metro rides, coffee, snacks, random museum entry, another coffee, water, SIM card, whatever. You don’t notice it til it’s gone.

I started keeping better track lately, but curious how other folks handle this.

Do y’all just keep notes? Use some tool? Or just accept the chaos?
