Watch out for horse boxes too!
Sneaky ;o) I'd also consider staying around Betws Y Coed, if you want cheap as chips perhaps somewhere like here:
Bunkhuts If you go to Betws though stay clear of the Old Stables for food. Not the best pub grub. Far better is the Conwy Falls Cafe up the road towards Penmachno or if you'd rather not drive then there's a small Pizza place Caban y Pair opposite the chippy. Its BYO for drink but the pizzas are fantastic.
Staying in Conwy on the coast could be another option. Lots of pubs there and a good Italian, Alfredos at the top of the high street.
