Hi there. You no need to long time to prepare, some accommodation put down in their welcome book all info you need or if you need some particular answers they are happy to help.About tram, you can use it in any day ( was really heavy rain when I went last time). But if you wanted to have a stunning view from cable car need to be sunshine and no wind ( well, not to much). They are not on in these kind of weather.Visiring mine are usual opened. Tram has two lines make it one. I mean on the way to summit, or on your way back you can come out from tram and visit mine, then continuu you4 journey. You also can travel by car or on the foot which is amazing in a beautiful day.At the visitor information centre in Llandudno you will find lots of things to do, include Conwy Castle, Snowdonia, Rhyl and many others. Llandudno is a ve4y clean little city and well preserved.To visit all around you probably need to stay 4-5 days , depends of your mobility, time you come out etc. , it's up to you. But one thing I can said , you can't get bored in this place.Remember to consider entrance fees for mines, for Castle ...Hope I was helpful, wish you all the best !
