Wow - a little surprised to hear that even your hotel would exchange at nearly the normal blue rate... although I suppose that they obviously have people they will exchange with at the blue rate, so it makes them money and (most probably) makes their guest happy as it's convenient and safe.

I hope you had a good visit. It's true that things are more complicated now, currency-wise especially, although my experience is that the cost of visiting/staying here is cheaper than it's been for awhile if you're coming with dollars and changing at blue rates, but certainly a lot more expensive than it's been (and should be) at official rates.
