this thread has a lot of detail!

In simple terms - is doing cash only feasible - wanting to do a less than 72 hour stay primarily to visit Disneyland and one day of sightseeing. So just some metro fares and food (which we could do at supermarket or 'western hotel' chains). Hotel prebooked and paid.

Interestingly discussion elsewhere rarely raises the issues of difficulty in spending.

Thanks for your thoughts.
