Thinking of booking a few days in Prague in January as a birthday treat and just wondered if there's much to do once you've seen the beautiful architecture? I believe the Christmas markets will still be on but even these have limits. I'm used to warm holidays where you can spend a morning or evening chilling outside in the sunshine! I'm a pretty active person and like to be doing stuff and would be a wee bit concerned we're going to end up at a bit of a loose end sometimes. Also is it reasonable enough to eat there? On a bit of a budget but don't mind paying for a few trips. Any advice/recommendations/thoughts on Prague in general are very welcome! Thanks
