As the title indicates, should I hold on to the US$ that we brought with us just in case -- whatever the "case" happens to be?
We have half a dozen credit cards to travel with and pay for anything we need.
We have a Schwab debit card to get local currency from ATM or use as another credit card.
We can transfer money in US$ from Schwab to Sacombank although it's not instantaneous. The fee is reasonable -- $25 flat rate; $10 less than with Citibank where we used to have an account (can't maintain the require balance of $5000 so we decided to close it).
What's your opinion and advice? Is there any advantage of keeping US$ in the safe?
