For years I have used the F/X Trader Cambio at the Hi-Lo. They know me and there is no long wait like at the banks. Same rate as the other Cambios and fewer prying eyes than at the ATM's. We stop by the Hi-Lo every few days anyway for snacks and bevs so it's convenient. I have used the ATM's in a pinch. But prefer the safety of Travelers Checks.
