Cheapest/best method in UK

That's incredibly vague. What are you doing, where? Travelling within cities? Inter-city travel? Village hopping? Wandering around sparsely-populated moors?

Well we have a general idea of our plans: 1. London 2. Birmingham 6. Nottingham 7. Liverpool 8. Dublin 9. Northern Ireland 10. Glasgow 11. Edinburgh 12. Newcastle 13. Middlesbrough 14. York/Leeds 15. Nottingham 16. London This is ambitious and I don't mind cutting Ireland out and simply sticking to England and Scottland to see two countries a bit more in depth. Just not sure if a bus-pass or a prepaid Eurorail or Britrail pass would be best. :)
Ry

The sights you mention are all on major rail lines(for the Britain part) so a rail pass may be a good deal, look at the Britrail information (Eurail really does not apply, it is valid for Ireland, but not the UK, and Ireland has very few rail lines) it can be a good deal since you are taking some long journeys and covering most of Britain. It is especially a good deal if "We" includes children 15 and under, as they travel free with an adult on a pass. If you decide to roam the countryside, then renting a car for a day or two is not the cheapest, but it is expediant, allowing you to cover an area quickly where a bus would be very limiting. As for Ireland, consider budget flights from Easyjet and RyanAir, even Aer Lingus has some good deals. Those will need to be locked in early to get a good price, plus with all air travel now, you will need to watch your luggage weight or you will pay big surcharges. I do not think a ferry in December would be a good option, but just my preference. Given the time you have, you might consider using a concept of finding several "bases" where you could stay say a week, then day trip or even overnight out of there. It would provide for less hauling of stuff and transfer time to set up lodging and you may get a better per night rate, even with staying a night someplace even though you have a room already elsewhere. You may even be able to leave bags someplace in Britain while you visit Ireland. Lots of options, some of the places you mention hold little charm for me, and I would probably look at more rural areas, but I think you are on to a good trip.

Just curiosity, as I know that this British journey is to keep your clock ticking whilst waiting to return to the frozen country of Switzerland, but how did you come up with the list of places? I agree that some of places on the list are not usually on most peoples' top 20. Have you been to the UK many times before? Are you traveling to the northeast just to see the Transporter Bridge?

Haha no problem, I'm a footballer. So some of those places lead me in directions where I can catch some matches. Also, I've been to England before, and am more interested in some smaller things than typical tourist stuff. That list is subject to change a bit, but it has my
Major points definitely :)

So, Birmingham, eh? Villa, Baggies, Blues, Sky Blues, Saddlers, or Woollie Wanderers?
