That sounds great.
Prague is a wonderful town. beautiful sights, good cheap food, and a spirit that is unique. I'm moving to Britain to do postgraduate study in Central European history. Part of how I decided that specialty was thinking of where I would like to go to do my research, and answering - Prague.
You took the fancy route, which I'm sure is lovely and romantic. But if you have a very tight budget you can make it quite well there too. We stayed in a apartment building that made extra cash by renting out empty apartments to tourists. It wasn't glamorous, but it was a decent, big room for less than 10 dollars (about 5 pounds) a night for two people. It wasn't in the center of town, but we got to see how people really live, and it was right next to a Metro stop so anywhere in town was just a few minutes away.
Sounds like a nice trip. I'm jealous, I'd love to go back. And the good news is, once we live in Britain, its not far away.
