Personaly, I wire sometimes - $10-15,000 w/ no paperwork.
Oftentimes I'll carry $5-6-7-8,000.
And again, I'll cash checks at the cambio.
Multifunctional, you might say !!
Cobraboy's suggestion is very uncomplicated - you can cash whatever you want at the cambio.
For those who might say, " I would never carry $8,000 on my trip"............ I say that walking out of the cambio is a certain giveaway that you have money in your pocket.
Any traveler might have no money - the cambio customer has just "loaded up".
Whichever you decide - always use caution and discretion and be aware.
