Cheers.
This is all purely a guess

But I don't mind taking a Fermi stab...
It's likely the both would be accepted - they are major currencies. On a hunch, perhaps EUR would be more accepted, because it's easily traded in demand with the neighbours of Czech Republic. Another view: I checked the number of CZK you would get vs 1 USD and 1 EUR and the trend graphs over the last month. It shows a decreasing trend for the CZK v USD (i.e. you're getting less CZK per 1 USD over the last month) whereas the CZK v EUR is holding steadier. So not only are EUR a steadier currency and may be more preferred (at least until the USD shows solid signs of recovery), you're likely not to have to play the exchange rate game as much with EUR compared to USD.
In the end, it probably matters squat (i.e. you're not changing huge amounts nor playing the currency game, so even if you had a small loss it wouldn't matter), and keeping some CZK isn't disastrous until Czech Republic join the EUR, which may not happen for a while, and some people might want to go back to PRG some time.
