I always stay in Hradec and its not that bad! Its about 30 minutes by train from pardubice, I think there are some that are even quicker (20ish minutes). You can use the following link to get the train times and fares and it has an english translation. http://jizdnirady.idnes.cz/vlakyautobusy/spojeni/
Its very good, I ordered mine last week and they arrived today. I was a bit dubious at first but thought that if it was posted on here then it must be ok
