Say you're making a quick trip (under 24 hours). How many dollars in cash do you bring? How many fives and singles? How many (if any) cash pesos is it good to have? Should you get pesos from an ATM or a casa de cambio? How much of a problem is it if you don't have small denomination bills in pesos? Do you use credit cards in TJ?
What's the max cash you can bring, without a serious risk that the cops will green light you getting robbed because of the cut they'll get?


I don't normally bring peso's, it just makes it harder to deal with and everything there is priced in dollars. I have heard a peso goes further than a dollar but to me it isn't worth the effort.
I usually bring about $300 for one evening trip. I try to bring a variety of $10s and $20s. I don't bring $1s, the mesero's can always make change. Make sure to save at least $5 to get back to the border.
Roughly, about $100 for fichas, $100 to $120 for one trip arriba (including tip), $30 or so for drinks (I am not a big drinker). That leaves $50 or so for other tips, transportation, and a little food it I get hungry.
