Personally I bring all cash and a higher limit C.C. for emergency's. I bring a lot of denominations as well. (1's, 5's, 10's). I also exchange for local currency. With that being said it tends to be a lot of bills on hand. Usually I use the in room safe's. Many place's that don't have them in room will have safes in the office. I also always bring a pacsafe with me as it can come in handy. http://www.pacsafe.com/travelsafe-5l-portable-safe.html There are different sizes available depending on your needs. Between both I can secure my cash and valuables. I simply take a little of both (US & J) for the day and I'm on my way.
