Fresh Cash 14 April

Read last night before I hit the hay near 1am that fresh cash only accepted at money exchange stations. Bills over a buck've gotta be year 2000+ issue, meaning I gotta get to a bank and withdraw dough with special requests.

But is that smart? And how much?

Also says here don't walk around with a wad of cash, making the logistical implementation of currency exchange a complete blast.

Travelers cheques an option? How widely accepted?

Research required. Can't do anything today anyway, accidentally left wallet at home.

And how much cash withdraw or assign to cheques? I only got liquid $850 to play around with until I arrive that Friday morning - everything above that is a credit card withdrawl
