My wife and I, along with another couple are extending our Viking river cruise, by taking a bus from Passau, Germany to Prague. We are planning on arrive in Prague around noon. We are in our early 70's and active.
We are not sure what we sill do the first day and night we arrive.
Second day we would like to book a Prague city tour during the day and maybe see an opera that evening.
Third day we would like to take a day trip, possibly to the Bohemian Switzerland National Park.
Fourth day we will take the train to Ljubljana, then a bus to Lake Bled for two days.
Any suggestions, critics would be appreciated.
Thanks
