I've stayed at the Norbreck Castle a 5 or 6 times over the last few years with my children. It's a fair way out of central Blackpool and a taxi from blackpool north railway station costs approximately 8 pounds, there's a tram stop opposite the hotel and its between £1.60 to £2.40 adult fare to blackpool, depending where you get off.
It's a large hotel so you can have quite a walk to your room depending which wing your room is in. To be honest, I've never had a bad room yet though I've had a couple with not the best of views, but I don't go to blackpool to sit looking out of the window so no problem.
It's disabled friendly with an access ramp and disabled toilets around the hotel.
This hotel has some good facilites, a leisure centre with sauna, swimming pool and gym which residents can use for free, an amusement arcade, a games room with a couple of pool tables and a air hockey table, and a free 32 seat cinema showing films at set times during the day/evening.
There's entertainment every night in the conservatory bar, there's also a pub in the hotel with a big screen, and for some reason drinks are a pound cheaper here, and it's common to see guests buying drinks here and going back to the entertainment with them, I do it myself.
Meals are self service with set times for evening meals, you book a time slot every morning, breakfast is a two hour period where you help yourself so you can be faced with a queue here at times.
This hotel gets mixed reviews around the internet but I've never had a bad time here and it's a place where there's something to do and keep your kids amused if you don't fancy going out.
