Most people cannot get to Cardiff by Tardis, but those catching ferries from Rosslare to Pembroke
will have a truly intergalactic experience when they get there
Doctor Who has been filmed in Cardiff for several years and a new Doctor Who Experience facility has now opened its doors - presumably by sonic screwdriver - in Cardiff Bay.
Fans can enjoy meeting all the scariest monsters in the history of the series, including the daleks, cybermen and sontarans.
The Tardis itself provides plenty of fun, with a great chance to ride in the famous dimension-defying blue police box and discover alien worlds.
Fans of the series can also find out more about Doctors of yesteryear by tracing the show back to its origins in 1963, when William Hartnell became the first timelord.
Each regeneration has brought not only a new face but new costumes as well, so it will be possible to view Tom Baker's scarf, Peter Davidson's cricket sweater and Sylvester McCoy's umbrella.
The attraction will certainly be guaranteed to exterminate any possibility of boredom and can form the centrepiece of a great visit to Cardiff.
A compact city of 346,000 people, the Welsh capital is blessed with having most of its attractions within easy reach of each other.
Cardiff Bay itself has plenty of places to eat and drink, as well as historic buildings such as the Norwegian Church, where the list of baptisms includes children's author Roald Dahl.
The Bay has even appeared in episodes of Doctor Who, as have other parts of the city in the spin-off series Torchwood.
Cardiff Castle is among the other attractions of the city, while those wanting to enjoy a trip to the beach may want to head down the road to Barry, where the shops by the beach will provide a reminder of another TV series - the comedy Gavin and Stacey.
