For most people who visited these parts of the world, Cardiff is Wales and it's only natural to be so, as it hosts half of the country's population. Tourists are not going to fill the hotels simply because of these numbers, but for the numerous landmarks and attractions. Once the accommodation issue is out of the way, you can start with visiting the Senedd, Pierehead building or the Llandaff Cathedral. If you are more into sports, than the Millennium Stadium is the place to be, while art buffs shouldn't miss the Wales Millennium Centre.

Last both not least, the ones who love old castles and forts have all the reasons to leave the hotel and check out Cardiff Castle, Castell Coch or St Fargans Castle. These objectives close to the city and there are many ways to get there quickly.
