Do you mean St Fagans? Theres lots of shots there, the tricky bit is getting the building without people standing in the way. Lots of the building are dark inside, and a tripod is going to be akward as some are small and theres lots of people about. Check out the castle/manor house bit, lots of flowers in the garden (if they are out yet) there were otters in the lake last time I was there.
Loads of detail shots like windows, bee hives, items inside the houses and the iron mongers shop (a load of detail shots in there). The farm is worth a look too.
Apart from the insides of the houses theres little shelter, so if the weathers bad you could get soaked.
